Config is ok assuming that R4 has path to 2.2.2.1 and that bridge-group 1 is
on e0 of R2 and R4. Better to use loopback on R1 and distribute route
to both R2 and R4. Check with sh dlsw cap on R1 for the two peers.
In config both peers will be active. R2 is the preferred peer but R4
is also active(capable). If only one peer is desired active need to use
backup-peer
on R1. If R1 receives a reply explorer or NB name-recognized from R4 before
R2 then the connection can still be made through the higher cost peer.
Some points on dlsw peer cost:
1. default cost is 3, range is 1-5
1. lowest peer cost will be preferred.
2. remote-peer cost overrides local-peer cost.
Given the restrictions I would configure it as:
R1:
dlsw remote-peer 0 tcp 2.2.2.2 cost 1
dlsw remote-peer 0 tcp 4.4.4.4 cost 5
R2:
dlsw local-peer peer-id 2.2.2.2 prom
R4:
dlsw local-peer peer-id 4.4.4.4 prom
Or, if only one active peer is desired:
R1: dlsw remote-peer 0 tcp 4.4.4.4 backup-peer 2.2.2.2
