Configuration procedure
1. Configure IP addresses and masks for the interfaces according to Figure 93. (Details not shown.)
2. Enable IS-IS to advertise host routes with LSR IDs as destinations:
# 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 ethernet 1/1
[RouterA-Ethernet1/1] isis enable 1
[RouterA-Ethernet1/1] isis circuit-level level-2
[RouterA-Ethernet1/1] 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
[RouterB-isis-1] network-entity 00.0005.0000.0000.0002.00
[RouterB-isis-1] quit
[RouterB] interface ethernet 1/1
[RouterB-Ethernet1/1] isis enable 1
[RouterB-Ethernet1/1] isis circuit-level level-2
[RouterB-Ethernet1/1] quit
[RouterB] interface pos 5/0
[RouterB-POS5/0] isis enable 1
[RouterB-POS5/0] isis circuit-level level-2
