<Sysname> system-view
[Sysname] interface gigabitethernet 2/1/1
[Sysname-GigabitEthernet2/1/1] isis enable
[Sysname-GigabitEthernet2/1/1] isis circuit-level level-1
Related commands
is-level
isis circuit-type p2p
Use isis circuit-type p2p to configure the network type of an interface as P2P.
Use undo isis circuit-type to remove the configuration.
Syntax
isis circuit-type p2p
undo isis circuit-type
Default
The network type of an interface depends on the physical media. (The network type of a VLAN interface
is broadcast.)
Views
Interface view
Predefined user roles
network-admin
Usage guidelines
Perform this configuration only for a broadcast network with only 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, configure the network type of attached interfaces as P2P
to avoid DIS election and CSNP flooding. This saves network bandwidth and speeding up network
convergence.
Examples
# Configure the network type of GigabitEthernet 2/1/1 as P2P.

isis cost
Use isis cost to set the IS-IS cost for an interface.
Use undo isis cost to remove the configuration.
