The L2 In-place Adjacency Replacement (IAR) feature for EVPN VXLAN optimizes internal data structures in EOS, reducing the convergence time necessary when remote VTEPs lose connectivity to an Ethernet Segment (ES).

Configuration just needs the following command:

router bgp 65200
   !
   address-family evpn
      layer-2 fec in-place update

Which component of AVD is impacted

eos_cli_config_gen

Use case example

Improve convergence in A/A multihoming deployments

Describe the solution you would like
