Configuring P2P Network Type For An Interface; Configuring Is-Is Route Control; Configuration Prerequisites - HP 6125XLG Layer 3 - Ip Routing Configuration Manual

Level-2) neighbor relationships, configure the circuit level for its interfaces as Level- 1 (or Level-2) to limit
neighbor relationship establishment.
To configure the IS level and circuit level:
Step
1. Enter system view.
2. Enter IS-IS view.
3. Specify the IS level.
4. Return to system view.
5. Enter interface view.
6. Specify the circuit level.

Configuring P2P network type for an interface

Perform this task only for a broadcast network that has up to two attached routers.
Interfaces with different network types operate differently. For example, broadcast interfaces on a
network must elect the DIS and flood CSNP packets to synchronize the LSDBs, but P2P interfaces on a
network do not need to elect the DIS, and have a different LSDB synchronization mechanism.
If only two routers exist on a broadcast network, configure the network type of attached interfaces as P2P
to avoid DIS election and CSNP flooding, saving network bandwidth and speeding up network
convergence.
To configure P2P network type for an interface:
Step
1. Enter system view.
2. Enter interface view.
3. Configure P2P network type for an
interface.

Configuring IS-IS route control

Configuration prerequisites

Before the configuration, complete the following tasks:
Configure IP addresses for interfaces to ensure IP connectivity between neighboring nodes.

By default, an interface can establish
either the Level-1 or Level-2
adjacency.

By default, the network type of an
interface depends on the physical
media. The network type of a
VLAN interface is broadcast.
