Figure 78. Adding segment numbers to bridge interfaces
In Figure 78 we enable interfaces for SRB, and add a segment number to
each. We enable interfaces 2, 3, 4, and 5, the last is our LEC. The segment
numbers are set as follows:
• interface 2 - segment number D21
• interface 3 - segment number D22
• interface 4 - segment D23
• interface 5 (the LEC) - segment F0D
See Figure 79. Now the MSS client configuration is complete.
The route from the legacy token-ring LAN to the legacy Ethernet would be as
follows: frame from local segment D21 -> bridge 1 -> segment 408 -> bridge 1
-> segment F0D (S1TokenRing ELAN) -> MSS Router -> S1Ethernet.
