Basic SRB with Spanning-Tree Explorers Example

Figure 55 illustrates a simple two-port bridge configuration. Token Rings 129 and 130 are connected through the router.

The example that follows routes IP, but source-route bridges all other protocols using spanning-tree explorers:

interface tokenring 0

ip address 131.108.129.2 255.255.255.0 source-bridge 129 1 130 source-bridge spanning

multiring all

!

interface tokenring 1

ip address 131.108.130.2 255.255.255.0 source-bridge 130 1 129 source-bridge spanning

!use RIFs, as necessary, with IP routing software multiring all
