Configuring Attributes for CSNPs
Context
On a broadcast link, CSNPs are periodically sent by a DIS device. If a device detects that its LSDB is not synchronized with that on its neighboring device, the device will send PSNPs to apply for missing LSPs.
On a P2P link, CSNPs are sent only during initial establishment of neighboring relationships.
Procedure
- Run system-view
The system view is displayed.
- Run interface interface-type interface-number
The interface view is displayed.
- On an Ethernet interface, run undo portswitch
The interface is switched to Layer 3 mode.
By default, an Ethernet interface works in Layer 2 mode.
The mode switching function takes effect when the interface only has attribute configurations (for example, shutdown and description configurations). Alternatively, if configuration information supported by both Layer 2 and Layer 3 interfaces exists (for example, mode lacp and lacp system-id configurations), no configuration that is not supported after the working mode of the interface is switched can exist. If unsupported configurations exist on the interface, delete the configurations first and then run the undo portswitch command.
If many Ethernet interfaces need to be switched to Layer 3 mode, run the undo portswitch batch interface-type { interface-number1 [ to interface-number2 ] } &<1-10> command in the system view to switch these interfaces to Layer 3 mode in batches.
- Run isis timer csnp csnp-interval [ level-1 | level-2 ]
The interval at which CSNPs are sent is set on the specified interface.
By default, the interval at which CSNPs are sent on a broadcast network is 10 seconds.
Configure Level-1 and Level-2 only when a broadcast interface is specified.
- Run commit
The configuration is committed.
