Selected Answer: A
This is the standard approach for EVPN Anycast Gateway: All IRBs for a given subnet (across 7 PEs, in this case) share: The same IP address (default gateway for hosts) The same MAC address (Anycast MAC, usually set manually or derived) This provides seamless failover and consistent gateway behavior.
