Configuring Area Authentication; Configuring Routing Domain Authentication - HP 6125XLG Configuration Manual

Step
3. Specify the authentication
mode and password.

Configuring area authentication

Area authentication prevents the router from installing routing information from untrusted routers into the
Level- 1 LSDB. The router encapsulates the authentication password in the specified mode in Level- 1
packets (LSP, CSNP, and PSNP) and checks the password in received Level- 1 packets.
Routers in a common area must have the same authentication mode and password.
To configure area authentication:
Step
1. Enter system view.
2. Enter IS-IS view.
3. Specify the area
authentication mode and
password.

Configuring routing domain authentication

Routing domain authentication prevents untrusted routing information from entering into a routing
domain. A router with the authentication configured encapsulates the password in the specified mode
into Level-2 packets (LSP, CSNP, and PSNP) and check the password in received Level-2 packets.
All the routers in the backbone must have the same authentication mode and password.
To configure routing domain authentication:
Step
1. Enter system view.
2. Enter IS-IS view.
