DLSw+ Using TCP Encapsulation with Local Acknowledgment—Peer Group
Configuration Example 1
Figure 132 illustrates border peers with TCP encapsulation. Router A is configured to operate in
promiscuous mode, and border peers Routers B and C forward broadcasts. This configuration reduces
processing requirements in Router A (the access router) and still supports any-to-any networks.
Configure Border peer B and C so that they peer to each other.
