Enabling The Logging Of Neighbor State Changes; Enabling Is-Is Ispf - HP 6125XLG Layer 3 - Ip Routing Configuration Manual

Step
1. Enter system view.
2. Enter IS-IS view.
3. Specify a host name
for the IS and enable
dynamic system ID to
host name mapping.
4. Return to system view.
5. Enter interface view.
6. Configure a DIS name.

Enabling the logging of neighbor state changes

With this feature enabled, the router delivers logs about neighbor state changes to its information center.
The information center processes the logs according to user-defined output rules (whether to output logs
and where to output). For more information about the information center, see Network Management and
Monitoring Configuration Guide.
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.

Enabling IS-IS ISPF

When the network topology changes, Incremental Shortest Path First (ISPF) computes only the affected
part of the SPT, instead of the entire SPT.
To enable IS-IS ISPF:
Step
1. Enter system view.
2. Enter IS-IS view.
