2. Run:
interface interface-type interface-number
The interface view is displayed.
3. Run:
isis timer csnp csnp-interval [ level-1 | level-2 ]
The interval for sending CSNPs is set.
CSNPs are transmitted by the Designated IS (DIS) to synchronize an LSDB in a broadcast
network. If the level is not specified, the timer of the current level is configured.
Configuring the Interval for Retransmitting LSPs
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number
The interface view is displayed.
3. Run:
isis timer lsp-retransmit retransmit-interval
The interval for retransmitting LSPs on a P2P link is set.
On a P2P link, if the local router does not receive the response within a period of time after
it sends an LSP, it considers that the LSP is lost or dropped. To ensure the reliable
transmission, the local router retransmits the LSP according to the retransmit-interval. By
default, the interval for retransmitting the LSP packet on the P2P link is 5 seconds.
The LSPs sent on a broadcast link do not need any response.
Configuring the Minimum Interval for Sending LSPs
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number
The interface view is displayed.
3. Run:
isis timer lsp-throttle throttle-interval [ count count ]
The minimum interval for sending LSPs is set.
count: specifies the maximum number of LSP packets to be sent within the period
specified by throttle-interval. The value ranges from 1 to 1000.
You can set the minimum interval for sending LSPs on an IS-IS interface, that is, the delay
between two consecutive LSPs. The value is also the interval for sending fragments of a
CSNP.
