when virtual-gateway-address ( VGA) is used, a VRRP based MAC “00:00:5e:00:01:01” is used on both the spines, so MAC synch is not needed

To stop the CLI knob, 'no-gateway-community' is used

When you apply a VRF export policy for the VRF Table on PE Routers in VPNs, routes from VPN routing instances are advertised to other PE routers based on this policy, whereas the BGP export policy is ignored.

Apply both the VRF export and BGP group or neighbor export policies (VRF first, then BGP) before routes from the vrf or l2vpn routing tables are advertised to other PE routers.

All paths with the same neighboring AS, learned by a multipath-enabled BGP neighbor, are considered.

To support pinging on the virtual gateway IP address, you must include both the virtual-gateway-accept-data statement and

the preferred statement at the [edit interfaces irb unit] hierarchy of the preferred virtual gateway.
