Specifying The Interval For Sending Is-Is Csnp Packets; Configuring A Dis Priority For An Interface; Disabling An Interface From Sending/Receiving Is-Is Packets - HP FlexFabric 12900E Series Configuration Manual

On a P2P link, Level-1 and Level-2 hello packets are advertised in P2P hello packets. You do not
need to specify Level-1 or Level-2.
To specify the IS-IS hello multiplier:
Step
1. Enter system view.
2. Enter interface view.
3. Specify the hello multiplier.

Specifying the interval for sending IS-IS CSNP packets

On a broadcast network, perform this task on the DIS that uses CSNP packets to synchronize
LSDBs.
To specify the interval for sending IS-IS CSNP packets:
Step
1. Enter system view.
2. Enter interface view.
3. Specify
sending CSNP packets on
the DIS of a broadcast
network.

Configuring a DIS priority for an interface

On a broadcast network, IS-IS must elect a router as the DIS at a routing level. You can specify a DIS
priority at a level for an interface. The greater the interface's priority, the more likely it becomes the
DIS. If multiple routers in the broadcast network have the same highest DIS priority, the router with
the highest MAC address becomes the DIS.
To configure a DIS priority for an interface:
Step
1. Enter system view.
2. Enter interface view.
3. Configure a DIS priority for
the interface.

Disabling an interface from sending/receiving IS-IS packets

After being disabled from sending and receiving hello packets, an interface cannot form any
neighbor relationship, but can advertise directly connected networks in LSPs through other
interfaces. This can save bandwidth and CPU resources, and ensures that other routers know
networks directly connected to the interface.
