Configuring the Interval for Sending PSNP Messages

Partial sequence number message PSNP (Partial SNP): It only lists the sequence numbers of the most recently received LSPs, and can confirm multiple LSPs at once. When it is found that the LSDB is not synchronized, PSNP is also used to request neighbors to send a new LSP. Users can use the command set protocols isis area-tag <text> interface <interface-name> psnp-interval <psnp-interval> to configure the PSNP interval in seconds. The psnp-interval <psnp-interval> value is an integer ranging from 1 to 120 seconds. The default value is 10 seconds.

The following commands configure the PSNP interval.
