This behavior has been improved from Cisco ACI Release 3.0(1k) by the enhancement, CSCve29663. Note:The Catalyst 6xxx family of switches does NOT support an external MLS-RP at this time. The old leaf that receives this notification will delete its old endpoint entry and create a bounce entry, which will point to the new leaf. Please refer to the L3Out Transit Routing section for details about the Export Route Control Subnet scope. The Shared Route Control Subnet and Shared Security Import Subnet scopes are typically configured on the same L3Out subnet entry. This means that by default one L3Out SVI on a given leaf cannot run multiple routing protocols. This document focuses on EVPN Multi-Site architecture, so the site-internal overlay configuration for dual- and multiple-autonomous-system designs is omitted. Set the power supply switch to the correct voltage setting. Figure 21 shows a conceptual image of an L2BD in which the Unicast Routing option is disabled. The topology with a normal port channel or access port (For example, one border leaf switch for each firewall) for two border leaf switchesone for eachis supported regardless of the generation of the leaf switch, starting from Cisco ACI Release 2.2(2), regardless of whether a multiple-pod or single-pod design is used. ip summary-address eigrp /. You can create an ACL to match your PC traffic based on source, destination IP addresses, and source/destination port numbers. Note:The set port speed {mod_num/port_num} auto command also sets the duplex mode to auto. First we clear the counters, then show mac, send three pings, and then show mac again to see on which channel the ping responses were received. In most cases, this field can be left as the default. terminates on a Cisco switch, you can run PAgP protocol on the MEC. A Cisco StackWise Virtual active switch that detects a dual-active condition shuts down all of its non-SVL interfaces to remove itself from the network. In the second step, the endpoint with MAC2 and IP2 on LEAF2 moves to LEAF4, and the new local endpoint is created on LEAF4. Verify that EtherChannel is supported on the ports, show port capabilities appears in versions 4.x and greater. They have portfast disabled, PAgP (EtherChannel) mode is set to auto (it channels if asked to channel), and the trunking mode (DTP) is set to auto (it trunks if asked to trunk). This capability provides flexibility for existing deployments and transport independence for the site-external network. The VRF member name must match the VRF context name in the next step. Note: Site-external EVPN peering is always considered to use eBGP with the next hop the shared border. Similarly, the route target can be derived automatically by using the BGP autonomous system followed by the VNI defined as part of the VRF instance (ASN:VNI). Before you exchange the switch hardware, you can try a few things: Reseat the module in the switch. It also introduces split-horizon rules to help ensure that traffic entering the BGW from one flood domain does not return to the same flood domain. From the point of view of the site-external network, no specific requirements are demanded apart from IP transport reachability between the BGWs and accommodation of an increased Maximum Transmission Unit (MTU) packet size. BD subnets still need to be marked as Advertised Externally. Cisco Catalyst 3750 Switches support various QoS features such as classification, marking, policing, queueing and scheduling. This feature was introduced in APIC Release 4.1(1). There are no specific requirements for this document. When server2 takes over the active role, server2 sends GARP and 192.168.2.100 is now learned on Leaf2 E1/2. For this flow, a nonborder leaf is an ingress leaf and a border leaf is an egress leaf. LEAF2 will then bounce the packet to the new LEAF4 based on its bounce entries. Default-route advertisement in OSPF Regular area. Default Route Leak Policy for OSPF in GUI (APIC Release 3.2). The configuration for a BGW to a shared border with a site-external eBGP underlay is shown here. Then, the CoS-DSCP table calculates and resets the DSCP value to 0. hardware forwarding. More are added every day. You can also configure egress queue 1 as the priority queue. Similar connectivity can be achieved by the other sites, so that every BGW has redundant connectivity to the Layer 3 cloud, which also reduces the convergence time in a link-failure scenario. VLANs are also described as broadcast domains. We just show the received packets from SwitchB because the transmit packets are further down in the show mac display). By default, the modules are set to auto trunking and negotiate mode, which means that they trunk if the other side asks them to trunk, and they negotiate whether to use the ISL or 802.1q method for trunking. Retransmit Interval (sec) The interval between OSPF LSA (link-state advertisement) retransmissions. If nondefault Egress is used, contract may be applied on each border leaf. EIGRP (IPv4) has been supported since APIC Release 1.1(1). Set Weight (BGP Weight) This is to set the BGP weight. However, Prevents IP addresses from remaining stuck to an endpoint, even when the IP address is no longer used, System > System Settings > Endpoint Controls > Rogue EP Control, Detects endpoints that move frequently and disables endpoint learning for these endpoints only. In fact, for internal MLS-RPs, the MLS-ID is normally not even an IP address configured on the router; since internal MLS-RPs are included automatically, it is commonly a loopback address (127.0.0.x). This section explains three types of configurations. From here, choose Documentation Home Page. However, border leaf may still learn remote IP endpoints from IP multicast routing packets, because of a limitation in the Cisco ACI IP multicast routing implementation. It discusses deployment options using the data-plane learning options listed in Table 1. The terms "workstation", "end-station", "server" are all used interchangeably in this section. In Figure 53, LEAF2 includes BD3 with 172.16.0.0/24 configured, which is why unexpected remote IP endpoint learning is not prevented in this scenario. However, Cisco ACI needs to know only the next hop (external router) for those prefixes. Until that happens, the bounce entry takes care of the traffic. The following list provides additional details for each parameter type: Path Type There are three Path types available in an L3Out, as shown in the following table: a physical port such as eth1/1 on a single leaf switch, a normal port-channel on a single leaf switch, a vPC that spans across two leaf switches. In addition to data-plane learning, Cisco ACI uses bounce entries to manage the old endpoint information on the original leaf. For example, if a frame with CoS 5 and the packet inside the frame with DSCP EF enters the switch, the CoS and DSCP labels are not changed. Learn more about how Cisco is using Inclusive Language. See other sections (such as the L3Out Transit Routing section) for detailed examples of route maps internally created by other components. This is applicable to the option at VRF only because the other options are available after Cisco APIC Release 5.2(1g) that doesnt support first-generation leaf switch anymore. The Disable Remote EP Learn feature was originally introduced to address scenario 3 in the L3Out endpoint learning considerations section. 0000008799 00000 n The switch also trusts and allows the traffic from the PC, and gives the same priority as the IP phone traffic. Once the penalty goes below half of the Reuse Limit, the penalty is completely removed from the route. As greater demands are placed on networks, the need for greater performance increases. motivation for local forwarding is to avoid unnecessarily sending data traffic over the StackWise Virtual link and thus reduce Configure the neighbor in the IPv4 unicast global address family (VRF default) to peer with the site-external loopback interface (loopback0) of the BGW. One is marking and the second one is policing. At this point, the remote endpoint still points to the old LEAF2 entry, instead of the new LEAF 3 entry, but this old remote endpoint will never be updated to point to LEAF3, nor will it age out because of the particular behavior on the L3Out connection, as described for scenario2 (stale remote endpoint example with L3Out incoming traffic) in Table 6. Also, there is no point in creating an L3Out subnet with an Export Route Control Subnet scope in this L3Out EPG because it will be ignored in both Transit Routing and BD subnet advertisement due to the Route Profile with Match Routing Policy Only in the Export Direction. The approach of building a network over the top without touching every switch offers simplicity, and such a network can be extended across multiple locations. This location information is placed in a Content Addressable Memory table (CAM - named for the type of memory used to store these tables). The Enforce Subnet Check option was first introduced in APIC Releases 2.2(2q) and 3.0(2h) with the following enhancement: CSCvf43074: ACI knob to limit IP EP learning to available BD subnets under the same VRF. ACI uses route maps internally for various purposes, such as infra MP-BGP, BD subnet advertisement to the outside, and Transit Routing, as mentioned in the previous sections. The Layer 2 VNI chosen refers to the vn-segment ID chosen in the previous step. Please note that Aggregate option for Export and Import scopes is supported only for 0.0.0.0/0 subnet. In the following, each step is briefly explained. Cisco recommends that you have knowledge of Configuring QoS. Queue 2 is the priority queue. Please be aware that, just like a normal BGP router, the summarization will not occur if no contributing routes exist in the IPv4/IPv6 BGP table for the user VRF on the border leaf. This optimization is achieved by equipping every VTEP with a first-hop gateway and the information needed to take the best path to a given destination. For purposes of this rule only, treat a workstation like a router. If BUM traffic reaches the BGW from the site-internal network, forwarding is allowed only to the site-external network, and if BUM traffic reaches the BGW from the site-external network, forwarding is allowed only to the site-internal network. The details are in the BGP protocol options VRF level subsection, below. In case the same SVI and its IP address need to be deployed on multiple L2 interfaces, the configuration shown in Figure 17 will achieve that. Unlike the BGW, the shared border is completely independent of any VXLAN EVPN Multi-Site software or hardware requirements, it is sloley a border node topologically outside of a single or multiple Sites. There are many components that add an IP prefix-list into a route map on a border leaf. When a BGP route status changes from available to unavailable or vice versa, a penalty of 1000 is added to the route. However, the sole focus of this document is on how this extension can be achieved by using EVPN Multi-Site architecture, an integrated interconnectivity approach for VXLAN BGP EVPN fabrics. The configurations are bandwidth shape, share, and limit. ACI uses MP-BGP and route target to leak an external route from one VRF to another. Set logging for spanning tree to the most verbose (Set logging level spantree 7). Warning:Whenever you make configuration changes to a router intended to be permanent, remember to save those changes with a copy running-config starting-config (shortened versions of this command include copy run start and wr mem). This can be used as an alternative for Aggregate Export/Import for an Export/Import Route Control Subnet scope in case an aggregation is required for a non-0.0.0.0/0 subnet. The third method, using Route Map/Profile in Export Direction, provides a configuration methodology like that for a normal router when you configure a route map and an IP prefix-list directly. Unlike an Export Route Control Subnet scope, this aggregate option for shared routes can be used not only for 0.0.0.0/0 but also for non-0.0.0.0/0 subnets. By adding a route-summarization policy to the L3Out subnet, as shown in Figure 45, the border leaf will try to create a Null-0 entry for the summarized route (192.168.0.0/16 in Figure 45), which will be advertised to its BGP peers. Table 3 lists the Cisco ACI leaf switches by generation. Define the neighbor configuration with the EVPN address family (L2VPN EVPN) for the site-internal overlay control plane facing the route reflector. Sometimes this causes the problem to disappear; this is a workaround, not a fix. Turn on the power supply switch. VOIP traffic needs to be assigned a DSCP value of EF: Traffic from TCP 1494 needs to be assigned a DSCP value of CS4: All other traffic needs to be assigned CS3: On the Cisco Catalyst 3750 Switch, policing can only be configured on the ingress port.
