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, PSNP) and check the password in received Level-2 packets.
All the routers in the backbone must have the same authentication mode and password.
Follow these steps to configure routing domain authentication:
To do...
Enter system view
Enter IS-IS view
Specify the routing domain
authentication mode and
password

Configuring System ID to Host Name Mappings

In IS-IS, a system ID identifies a router or host uniquely. A system ID has a fixed length of 6 bytes. When
an administrator needs to view IS-IS neighbor information, routing table or LSDB information, using the
system IDs in dotted decimal notation is not convenient. To solve it, you can configure the mappings
between system IDs and host names since host names are easier to remember and use.
Such mappings can be configured manually or dynamically. Note that:
Using the display isis lsdb command on a router configured with dynamic system ID to host name
mapping displays router names rather than system IDs.
If you configure both dynamic and static system ID to host name mappings on a router, the host
name for dynamic system ID to host name mapping applies.

Configuring a Static System ID to Host Name Mapping

Follow these steps to configure a static system ID to host name mapping:
To do...
Enter system view
Enter IS-IS view
Use the command...
isis [ process-id ] [ vpn-instance
vpn-instance-name ]
area-authentication-mode { md5
| simple } password [ ip | osi ]
Use the command...
system-view
isis [ process-id ]
[ vpn-instance
vpn-instance-name ]
domain-authentication-mode
{ md5 | simple } password [ ip |
osi ]
Use the command...
system-view
isis [ process-id ]
[ vpn-instance
vpn-instance-name ]
