have a couple of topologies set up wherein i use a bridge-group tied with an address (similar to the concept of svi in cisco-land). i've never been able to ping successfully between these addresses within the topology -- even though i've defined all of the bridge ports successfully, mac-addresses populate correctly, and arp even resolves.
when i run a tcpdump on the interfaces, i see the arp requests -- but no response. static arp entries on the device also don't help.
running cumulus vx 2.5.3 on vbox.
i can post additional configs if needed.
