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, and 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, saving network bandwidth and speeding up network
convergence.
Examples
# Configure the network type of VLAN-interface 10 as P2P.
<Sysname> system-view
[Sysname] interface vlan-interface 10
[Sysname-Vlan-interface10] isis enable
[Sysname-Vlan-interface10] isis circuit-type p2p
isis cost
Use isis cost to set the IS-IS cost for an interface.
Use undo isis cost to remove the configuration.
Syntax
isis cost value [ level-1 | level-2 ]
undo isis cost [ level-1 | level-2 ]
Default
No IS-IS cost is configured for an interface.
