VLT unicast routing

VLT unicast routing enables optimized routing where packets destined for the L3 endpoint of the VLT peer are locally routed. VLT unicast routing is supported for IPv4 and IPv6.

To enable VLT unicast routing, both VLT peers must be in L3 mode. The VLAN configuration must be symmetrical on both peers. You cannot configure the same VLAN as L2 on one node and as L3 on the other node.

  1. Enter the VLT domain ID in CONFIGURATION mode, from 1 to 1024.
    vlt-domain 
                                           domain-id
                                        
  2. Enable peer-routing in VLT-DOMAIN mode.
    peer-routing
  3. Repeat the steps on the VLT peer.

Configure unicast routing — peer 1

OS10(config)# vlt-domain 1
                                 OS10(conf-vlt-1)# peer-routing
