Benny,
Here's something from my notes... copied from a
discussion on here awhile back.
You would use port lists if you want to restrict dlsw
traffic. For example, say you have 3 routers.
Router 1 - Token 0, Ethernet 0
Router 2 - Token 0
Router 3 - Ethernet 0
You want the token rings to ONLY be able to
communicate with each other and not the ethernets.
You would use either port lists or ring lists
(same result different syntax). Those commands only
work for TR and Serial links.
If you want the ethernets to only be able to talk to
each other you have to use bgroup-list.
Router-A has two dlsw remote peers (150.150.10.3,
150.150.10.2) and 3 token ring interfaces:
Router-A"
!
source-bridge ring-group 100
dlsw local-peer peer-id 150.150.10.1
dlsw remote-peer 1 tcp 150.150.10.3 ('1' references
dlsw port-list 1)
dlsw remote-peer 2 tcp 150.150.10.2 ('2' references
dlsw port-list 2)
!
dlsw port-list 1 port tokenring0 tokenring1
dlsw port-list 2 port tokenring2
Explorers originating on a ring supported by
150.150.10.3 will be propagated out tok0 and tok1 by
Router-A but not out tok2.
