isis circuit-type p2p

Use isis circuit-type p2p to set the network type of an interface to P2P.

Use undo isis circuit-type to restore the default.

Syntax

isis circuit-type p2p

undo isis circuit-type

Default

The network type of an interface varies by physical media. (The network type of a VLAN interface is broadcast.)

Usage guidelines

Use this command only on a broadcast network with two attached routers.

Interfaces with different network types operate differently. For example, broadcast interfaces must elect a DIS and flood CSNP packets to synchronize the LSDBs. P2P interfaces do not need to elect a DIS, and use a different LSDB synchronization mechanism.

If only two routers exist on a broadcast network, set the network type of attached interfaces to P2P to avoid DIS election and CSNP flooding. This saves network bandwidth and speeds up network convergence.

Examples

# Set the network type of VLAN-interface 10 to P2P.

<Sysname> system-view
[Sysname] interface vlan-interface 10
[Sysname-Vlan-interface10] isis enable
[Sysname-Vlan-interface10] isis circuit-type p2p
