I'm using a Linux box with two network interfaces as bridge (br0) and one system (X) behind the bridge with its own IPv6 address configured. Its other end is connected to a router.
The bridge interface (br0) also has an IPv6 address configured. I am able to ping my router from X, but not able to ping br0. Similarly, I'm not able to ping X from br0.
I created a packet dump and saw neighbor solicitation and neighbor advertisement from both ends, but it's not getting updated in ip neigh show as REACHABLE. I'm unable to understand what's going on, since I'm not proficient with networking
Do I have to do anything to resolve this issue?
