> According to the dlsw+ design and implement guide, under an token envirorm
ent, If two routers connect to the same ring and they all do dlsw with the remo
te site, you'd better configure the router with the same virtual ring number, o
therwise explorer from remote site will comeing into the token ring and then re
send out to the wan with the other router.

group of r2 and r3 should has the same number, command such as "source-bridge
ring-group 200".

site to remote site communication? I mean prevent dlsw traffic from r1 to r4.
