Purpose
(Optional) Sets the router to purge LSPs received with
checksum errors.
Enters interface configuration mode.
(Optional) Configures the amount of time between each
LSP sent on an interface.
(Optional) Configures the interval at which periodic CSNP
packets are sent on broadcast interfaces.
• Sending more frequent CSNPs means that adjacent
routers must work harder to receive them.
• Sending less frequent CSNP means that differences
in the adjacent routers may persist longer.
(Optional) Configures the amount of time that the sending
router waits for an acknowledgment before it considers
that the LSP was not received and subsequently resends.
RP/0/RP0/CPU0:router(config-isis-if)#
retransmit-interval 60
[ level { (Optional) Configures the amount of time between
retransmissions on each LSP on a point-to-point interface.
• This time is usually greater than or equal to the
lsp-interval command time because the reason for
lost LSPs may be that a neighboring router is busy.
A longer interval gives the neighbor more time to
receive transmissions.
(Optional) Optimizes LSP flooding in NBMA networks
with highly meshed, point-to-point topologies.
• This command is appropriate only for an NBMA
network with highly meshed, point-to-point
topologies.
