Step 1
Enters the explicit path configuration mode. Identifer range is
1 to 65535.
explicit-path {identifier number [disable | index]}{
name explicit-path-name
}

name backup-srlg
Step 2
Specifies the IP address to be excluded from the explicit path.
index 1 exclude-address
192.168.92.1

RP/0/RP0/CPU0:router
router(config-expl-path)# index 1
exclude-address 192.168.92.1
Step 3
Specifies the IP address to extract SRLGs to be excluded from
the explicit path.
index 2 exclude-srlg 192.168.92.2
