Metric: 0 IS-Extended RouterB.00
Metric: 0 IS-Extended RouterC.00
Total Level-1 LSP count: 2 Local Level-1 LSP count: 1
The output verifies that IS-IS protocol is operational and the displayed link metrics (Metric: 10) are as configured.
Step 7
Configure the max-link-metric statement on Router B.
Example:
RP/0/0/CPU0:RouterB(config)# router isis ring
RP/0/0/CPU0:RouterB(config-isis)# max-link-metric
RP/0/0/CPU0:RouterB(config-isis)# exit
RP/0/0/CPU0:RouterB(config)#
Step 8
Commit your configuration.
Example:
RP/0/0/CPU0:RouterB(config)# commit
Step 9
Confirm the change in link metrics on Router B.
Example:
RP/0/0/CPU0:RouterB# show isis database

RouterB.01-00 0x00000001 0xc8df 800 0/0/0
Metric: 0 IS RouterB.00
Metric: 0 IS RouterC.00
Metric: 0 IS-Extended RouterB.00
Metric: 0 IS-Extended RouterC.00
Total Level-1 LSP count: 2 Local Level-1 LSP count: 1
The output verifies that maximum link metrics (63 for IPv4 and 16777214 for IPv6) have been allocated for the designated
links.
Step 10
(Optional) Verify the change in route prefixes on Routers A and C.
