Configuring A Dis Priority For An Interface; Disabling An Interface From Sending/Receiving Is-Is Packets; Disabling Hello Source Address Check For A Ppp Interface - HP MSR Series Configuration Manual

Step
1. Enter system view.
2. Enter interface view.
3. Specify the number of hello packets a
neighbor must miss before declaring
the router is down.

Configuring a DIS priority for an interface

On a broadcast network, ISIS 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 specify a DIS priority for an interface:
Step
1. Enter system view.
2. Enter interface view.
3. Specify 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 other routers know networks directly connected to the
interface.
To disable an interface from sending and receiving IS-IS packets:
Step
1. Enter system view.
2. Enter interface view.
3. Disable the interface from
sending and receiving IS-IS
packets.

Disabling hello source address check for a PPP interface

On a P2P link, IS-IS verifies the source IP address of the incoming hello packets is in the same network
segment as the IP address of the receiving interface. If not, it discards the hello packets, and no neighbor
relationship can be established with the peer router.
