Configuration procedure
1.
Configure IP addresses and masks for interfaces. (Details not shown.)
2.
Configure IS-IS to advertise interface addresses, including the loopback interface address:
# Configure Router A.
<RouterA> system-view
[RouterA] isis 1
[RouterA-isis-1] network-entity 00.0005.0000.0000.0001.00
[RouterA-isis-1] quit
[RouterA] interface gigabitethernet 1/1/1
[RouterA-GigabitEthernet1/1/1] isis enable 1
[RouterA-GigabitEthernet1/1/1] isis circuit-level level-2
[RouterA-GigabitEthernet1/1/1] quit
[RouterA] interface loopback 0
[RouterA-LoopBack0] isis enable 1
[RouterA-LoopBack0] isis circuit-level level-2
[RouterA-LoopBack0] quit
# Configure Router B.
<RouterB> system-view
[RouterB] isis 1
