The RIF of a source route frame from Host A to reach Host B routes from Ring 1, Bridge 5,
Ring 10, Bridge 6, to Ring 2. In hex, the RIF is 0830.0015.00a6.0020.

RSRB with TCP Encapsulation
Looking at Figure 4-27, Router A reaches Router B through an IP network. With TCP, the local
peer IP address is configured with one remote-peer statement, and the remote peer IP address
is also configured with another remote-peer statement. The router can also be configured to
acknowledge sessions destined for the remote peer by using the local-ack argument. The RSRB
configuration is shown in Example 4-10. You use the shaded source-bridge remote-peer
commands to define the local peer with the local IP address, and the remote peer with the IP
address of the remote router.
