Isis Cost - H3C S5820X Series Command Reference Manual

View

Default level
2: System level
Parameters
None
Description
Use the isis circuit-type p2p command to configure the network type for an interface as P2P.
Use the undo isis circuit-type command to cancel the configuration.
By default, the network type of an interface depends on the physical media. (The network type of a VLAN
interface is broadcast.)
Interfaces with different network types operate differently. For example, broadcast interfaces on a
network need to elect a DIS and flood CSNP packets to synchronize the LSDBs, and P2P interfaces on a
network need not elect a 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.
NOTE:
You can perform this configuration only for a broadcast network with only two attached routers.

• This command is not supported in loopback interface view.
