Configuring the Network Type of an Interface as P2P

Interfaces with different network types operate differently. For example, broadcast interfaces on a
network need to elect the DIS and flood CSNP packets to synchronize the LSDBs, while P2P interfaces
on a network need not elect the DIS and have a different LSDP synchronization mechanism.
If there are only two routers on a broadcast network, you can configure the network type of attached
interfaces as P2P to avoid DIS election and CSNP flooding, saving network bandwidth and speeding up
network convergence.
Follow these steps to configure the network type of an interface:
To do...
Enter system view
Enter interface view
Configure the network
type for the interface as
P2P
You can only perform this configuration for a broadcast network with only two attached routers.

Configuring IS-IS Routing Information Control

Configuration Prerequisites

Before the configuration, accomplish the following tasks:
Configure network layer addresses for interfaces, and make sure adjacent nodes are reachable to
each other at the network layer.
Enable IS-IS.
Use the command...
system-view
isis [ process-id ]
[ vpn-instance
vpn-instance-name ]
is-level { level-1 | level-1-2 |
level-2 }
quit
interface interface-type
interface-number
isis circuit-level [ level-1 |
level-1-2 | level-2 ]
Use the command...
system-view
interface interface-type
interface-number
isis circuit-type p2p
1-17
