2.4.5 Path Protection to Two-Fiber BLSR Connection Example
Use the command ENT-CRS-STS1:CISCO:STS-5-1&STS-6-1,STS-12-8&STS-13-8:CTAG1::2WAY;
to create a selector between 5/1/1 and 6/1/1 which is bridged to Ring 2 (12/3/2 and 13/3/2), as shown in
Figure 2-31.

The command also creates a selector between 12/3/2 and 13/3/2 to a bridge to Ring 1 (5/1/1 and 6/1/1),
as shown in Figure 2-32.

2.4.5 Path Protection to Two-Fiber BLSR Connection Example
Ring 1 = path protection
Ring 2 = Two-fiber BLSR
This example, illustrated in Figure 2-33, uses a path protection end-point with a drop on a two-fiber
BLSR and the west span of the two-fiber BLSR (Ring 2) for the active path of the circuit. The example
also uses multiport addressing for Ring 2 and is based on a multiport OC12-4 card (this is only important
for computing the STS AID for multiport cards) where 13/3/2 = STS-13-26 and where
26 = (((3-1)*12) +2).
