Adding a Static RIF Cache Entry for a Two-Hop Path Example

Configuring Source-Route Bridging BC-153

Figure 60 Assigning a RIF to a Source-Route Bridge

The static RIF entry would be submitted to the router on the left as follows:

rif 1000.5A12.3456 0630.0081.0090

Adding a Static RIF Cache Entry for a Two-Hop Path Example

In Figure 61, assume that a datagram was sent from a router on ring 21 (15 hexadecimal), across

Bridge 5 to ring 256 (100 hexadecimal), and then across Bridge 10 (A hexadecimal) to ring 1365

(555 hexadecimal) for delivery to a destination host on that ring.

Figure 61 Assigning a RIF to a Two-Hop Path

The RIF in the router on the left describing this two-hop path is 0830.0155.100a.5550 and is entered

as follows:

rif 1000.5A01.0203 0830.0155.100a.5550

SR/TLB for a Simple Network Example

In the simple example illustrated in Figure 62, a four-port router with two Ethernets and two Token

Rings is used to connect transparent bridging on the Ethernets to SRB on the Token Rings.
