5. Configure routing domain authentication. Specify the MD5 authentication mode and password
1020Sec on Router C and Router D:
[RouterC] isis 1
[RouterC-isis-1] domain-authentication-mode md5 1020Sec
[RouterC-isis-1] quit
[RouterD] isis 1
[RouterD-isis-1] domain-authentication-mode md5 1020Sec
[RouterD-isis-1] isis 1
Configuring BFD for IS-IS
Network requirements
• As shown in Figure 57, IS-IS is enabled on Router A, Router B and Router C that are reachable to
each other at the network layer.
• After the link over which Router A and Router B communicate through the Layer-2 switch fails, BFD
can quickly detect the failure and notify IS-IS of the failure. Router A and Router B then communicate
through Router C.

Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure IS-IS basic functions:
# Configure Router A.
<RouterA> system-view

[RouterA-isis-1] network-entity 10.0000.0000.0001.00
[RouterA-isis-1] quit
[RouterA] interface gigabitethernet 2/1/1
