Search for policy routing.

Policy routing isn't relevant.

In order to communicate across a LAN, two hosts must be in the same broadcast domain. Hosts in 192.168.51.0/24 cannot communicate with hosts in 192.168.52.0/24.

If I have all of the kvm guests on both hosts, together with the br0 bridge on both hosts, configured with addresses on the same a.b.c.0/24 network then will all communication on a.b.c.0/24 pass over br0 if the target address is on the other host?

kvmh1g1 eth0=192.168.51.100 kvmh1 br0=192.168.51.41

kvmh2 br0=192.168.51.42 kvmh2g1 eth0=192.168.51.200

In other words, with the address configuration given above, will traffic from 192.168.51.200 reach 192.168.51.100 via the cross-over cable between 192.168.51.42/192.168.51.41?
