iBGP

In this example we will create a EVPN Fabric name myfabric with the AS Number: 6512

The value in bgp_asn should between double quotes. Example:

global:
    ibgp:
      bgp_asn: "6512"

global:
  ibgp:
    bgp_asn: "65000.1"

To display BGP session in asdot format, you can add the following CLI with a policy.

netascode-bgw(config)# as-format asdot
netascode-bgw# sh bgp l2vpn evpn summary | begin Neighbor
