Specifying The Interval For Sending Is-Is Csnp Packets; Configuring A Dis Priority For An Interface; Disabling Source Address Check For Hello Packets On A Ppp Interface - HP 5500 EI series Configuration Manual

Step
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 the interval for
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 source address check for hello packets on a PPP
interface
On a P2P link, IS-IS checks the source IP address of hello packets from the peer. If the peer is not on the
same network, IS-IS discards the hello packets and does not establish neighbor relationship with the
peer.
An IS-IS PPP interface can have a peer on a different network. To establish neighbor relationship with the
peer, you must disable source address check for hello packets on the PPP interface.
To disable source address check for hello packets on a PPP interface:
