BSR 64000 Command Reference Guide
18-10
isis csnp-interval
Complete Sequence Number PDUs (CSNPs) hold a complete list of all LSPs in the
IS-IS routing database. CSNPs are sent periodically on all links, and the receiving
systems use the information in the CSNP to update and synchronize their LSP
databases. The designated router multicasts CSNPs on broadcast links in place of
sending explicit acknowledgments for each LSP.
By default, IS-IS sends CSN packets periodically. If the BSR is the designated router
on a LAN, IS-IS sends CSN packets every 10 seconds. If the BSR is on a
point-to-point interface, it sends CSN packets every 3600 seconds (once an hour).
Depending on your network topology you may want to modify the default interval to
protect against LSP flooding.
The isis csnp-interval command is used to adjust the IS-IS CSNP interval for intranet
connections if the intranet is a part of a multiaccess meshed network on the interface.
