Notes:

• The sample configuration above shows DLSw+ configured using border peers in order to demonstrate circuit setup between two routers not peered to one another. RouterA is configured to operate in promiscuous mode, and border peers (RouterB and RouterC) forward broadcasts. This reduces processing requirements in the access routers, and still supports any-to-any networks.
• The following table contains show dlsw peer output from each of the three routers.
