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.
In this case, you can configure dynamic system ID to host name mapping. To do so, you need to
configure a host name for each router in the network. Each router advertises the host name in dynamic
host name CLVs to other routers. At last, all routers in the network have all the mappings to generate a
mapping table.
In addition, you can configure a name for the DIS in a broadcast network to help check the origin of
LSPs in the LSDB.
Follow these steps to configure dynamic 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 ]
––
Specify a host name for
the router
is-name sys-name
Required
No specified by default.
Return to system view quit ––
Enter interface view
interface interface-type
interface-number
––
Configure a DIS name isis dis-name symbolic-name
Optional
Not configured by default.
This command takes effect only on a
router with dynamic system ID to host
name mapping configured.
This command is not supported on
P2P interfaces.
Configuring IS-IS GR
Restarting ISIS on a router will cause network disconnections and route re-convergence.
With the Graceful Restart (GR) feature, the restarting router, known as the GR restarter, can notify the
event to its GR capable neighbors, which, known as the GR helpers, will keep their adjacencies with the
router within a configurable GR interval. After the restart, the router contacts its neighbors to retrieve its
routing table.
During the whole process, the network keeps stable.
