Implementing MPLS Traffic Engineering
The following example shows the NHOP and NNHOP backup tunnels with excluded SRLG values.
RP/0/RSP0/CPU0:router# show mpls traffic-eng topology path dest 100.0.0.5 exclude-srlg
ipaddr
Path Setup to 100.0.0.2:
bw 0 (CT0), min_bw 0, metric: 30
setup_pri 7, hold_pri 7
affinity_bits 0x0, affinity_mask 0xffff
Exclude SRLG Intf Addr : 50.4.5.5
SRLGs Excluded :
Hop0:50.5.1.5
Hop1:50.5.1.1
Hop2:50.1.3.1
Hop3:50.1.3.3
Hop4:50.2.3.3
Hop5:50.2.3.2
Hop6:100.0.0.2
The following example shows an extract of explicit-path set to protect a specific interface.
RP/0/RSP0/CPU0:router#sh mpls traffic-eng topology path dest 10.0.0.5 explicit-path name
name
Path Setup to 100.0.0.5:
bw 0 (CT0), min_bw 9999, metric: 2
setup_pri 7, hold_pri 7
affinity_bits 0x0, affinity_mask 0xffff
SRLGs Excluded: 10, 30, 77, 88, 1500, 10000000
Hop0:50.3.4.3
Hop1:50.3.4.4
Hop2:50.4.5.4
Hop3:50.4.5.5
Hop4:100.0.0.5
