Enabling The Logging Of Neighbor State Changes - HP MSR2000 series Configuration Manual

Step
3. Configure a system ID to host
name mapping for a remote
IS.
Configuring dynamic system ID to host name mapping
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 must be modified, perform configuration on all routers.
You can configure dynamic system ID to host name mapping. To do so, you must configure a host name
for each router in the network. Each router advertises the host name in dynamic host name CLVs to other
routers. Then, 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.
To configure dynamic system ID to host name mapping:
Step
1. Enter system view.
2. Enter IS-IS view.
3. Specify a host name
for the router.
4. Return to system view.
5. Enter interface view.
6. Configure a DIS name.

Enabling the logging of neighbor state changes

Logging of neighbor state changes enables the router to output neighbor state changes to the console
terminal.
To enable the logging of neighbor state changes:
Step
1. Enter system view.
2. Enter IS-IS view.
3. Enable the logging of
neighbor state changes.
