Example for Configuring Dynamic Routing Protocols for Communication with an M-LAG

Example for Configuring Dynamic Routing Protocols for Communication with an M-LAG

Applicable Products and Versions

This example applies to CE16800, CE6881, CE6820, CE6863, CE5881, CE6881K, CE6881E, and CE6863K series switches running V200R020C00 or later versions.

For details about the mapping between software versions and switch models, see the Hardware Query Tool.

Networking Requirements

In Figure 1-22, SwitchB and SwitchC establish an M-LAG, and M-LAG member interfaces on SwitchB and SwitchC support dynamic routing protocols. You can configure dynamic routing protocols on SwitchA so that SwitchA can communicate with the M-LAG through Layer 3 routes.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure SwitchA, SwitchB, and SwitchC to establish an M-LAG.
    • Configure V-STP on SwitchB and SwitchC.
    • Configure a DFS group on SwitchB and SwitchC, and bind IP addresses of management interfaces to the DFS group.
    • Configure a peer-link between SwitchB and SwitchC.
    • Configure M-LAG member interfaces on SwitchB and SwitchC and an Eth-Trunk interface on SwitchA.
    • Configure Monitor Link on SwitchB and SwitchC.

      Monitor Link associates uplink and downlink interfaces to prevent user-side traffic from being discarded due to an uplink fault.

  2. Configure OSPF over M-LAG.
    • Configure OSPF on SwitchB, SwitchC, and SwitchD to implement Layer 3 connectivity.
    • Configure IPv4 addresses for OSPF over M-LAG on SwitchB and SwitchC.

      Configure different M-LAG IPv4 addresses on SwitchB and SwitchC. Otherwise, neighbor relationships of the routing protocol cannot be established.

    • Configure an IP address for SwitchA to establish OSPF neighbor relationships with M-LAG member devices.
  3. Configure OSPFv3 over M-LAG.
    • Configure OSPFv3 on SwitchB, SwitchC, and SwitchD to implement Layer 3 connectivity.
    • Configure link-local addresses for OSPFv3 over M-LAG on SwitchB and SwitchC.

      Configure different M-LAG link-local addresses on SwitchB and SwitchC. Otherwise, neighbor relationships of the routing protocol cannot be established.

    • Configure an IPv6 address for SwitchA to establish OSPFv3 neighbor relationships with M-LAG member devices.
  4. Configure BGP over M-LAG.
    • Configure BGP on SwitchB, SwitchC, and SwitchD to implement Layer 3 connectivity.
    • Configure IPv4 addresses for BGP over M-LAG on SwitchB and SwitchC.

      Configure different M-LAG IPv4 addresses on SwitchB and SwitchC. Otherwise, peer relationships of the routing protocol cannot be established.

    • Configure SwitchA to establish BGP peer relationships with M-LAG member devices (SwitchB and SwitchC).
  5. Configure BGP4+ over M-LAG.
    • Configure BGP4+ on SwitchB, SwitchC, and SwitchD to implement Layer 3 connectivity.
    • Configure IPv6 addresses for BGP4+ over M-LAG on SwitchB and SwitchC.

      Configure different M-LAG IPv6 addresses on SwitchB and SwitchC. Otherwise, peer relationships of the routing protocol cannot be established.

    • Configure SwitchA to establish BGP4+ peer relationships with M-LAG member devices (SwitchB and SwitchC) and import routes.
