Does Avahi work over a bridged network? (sh.itjust.works)

I have a network set up something like the following:

Device A &lt;---> Router A &lt;---> Router B &lt;---> Device B

where Router A is a tp-link Archer AX73, and Router B is a tp-link Archer C7. Router B is flashed with OpenWRT, and Router A is using stock firmware. Router B is set up to be a wireless bridge between Router A's network, and its own (it was set up using this guide).

What I am wondering is if Device A can find, say, Device B.local, using Avahi (assuming Device A, and Device B both have Avahi installed, and running), over this bridged network. So far, I haven't been able to get it to work, so I'm wondering if it is possible at all. I have read that Avahi only works on a local network, but I was wondering if it could be bridged.

UPDATE (2024-01-16T01:28Z):

The issues that I mentioned in this post have since been solved. The majority of the issues stemmed from the fact that the relay software that I was using, relayd, doesn't support ipv6. All the tests that I was conducting were defaulting to ipv6, so it was appearing like the bridge was failing unpredictably. Since that realization was made, and countermeasures were enacted, the problem was solved.

Traceroute from device in subnet A to device in subnet B

Router A
Router B
Device B

Note that the only way to do that in only two hops is to have the same router handle both subnets, contrary to what I said earlier.

To make sure that I understand correctly, are you describing something similar to what was described in this thread?

[–] eutampieri@feddit.it 1 points 10 months ago (1 children)

Hmmm it seems that router B there should be a bridge. However, how comfortable are you with routing in general?

Ha, depends what you mean by that. If you mean manually specifying routes in a router, I think I generally understand it, but I am not at all confident in my abilities.

Exactly that. Router A

ip address add 192.168.1.1/24 dev eth1
ip address add 10.0.0.1/30 dev eth2
ip route add 192.168.2.0/24 via 10.0.0.2

Router B

ip address add 192.168.2.1/24 dev eth1
ip address add 10.0.0.2/30 dev eth2
ip route add 192.168.1.0/24 via 10.0.0.1

Does this make it more clear?

Yes, thank you! Usually, however, most of my issues seem to stem from knowing where configs are, what tools to use for what, or where to find things in the router user interface, etc.

I definitely agree!
