All the routers in the backbone must have the same authentication mode and password.
Follow these steps to configure routing domain authentication:
To do… Use the command… Remarks
Enter system view system-view ––
Enter IS-IS view
isis [ process-id ] [ vpn-instance
vpn-instance-name ]
––
Specify the routing domain
authentication mode and
password
domain-authentication-mode
{ md5 | simple } password [ ip |
osi ]
Required
No routing domain authentication
is configured by default.
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:
z 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.
z 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… Use the command... Remarks
Enter system view system-view ––
Enter IS-IS view
isis [ process-id ] [ vpn-instance
vpn-instance-name ]
––
Configure a system ID to host
name mapping for a remote IS
is-name map sys-id
map-sys-name
Required
A system ID can only correspond
to a host name.
Configuring Dynamic System ID to Host Name Mapping
You need to configure a static system ID to host name mapping for any other router in a network.
When a new router is added into the network or a mapping needs to be modified, you need to perform
configuration on all routers.
