Setting the LSP Retransmission Interval
When LSPs are dropped, LSPs are retransmitted. Use the isis retransmit-interval
command in Interface Configuration mode to set the number of seconds between
retransmission of each LSP for point-to-point links, as shown below:
MOT(config-if)#isis retransmit-interval <seconds>
where:
seconds is the number of seconds between LSP broadcasts.
Setting the LSP Retransmit Throttle Interval
To configure the amount of time between any LSP retransmissions on a point-to-point
interface, use the isis retransmit-throttle-interval interface configuration command
in Interface Configuration mode as shown below:
MOT(config-if)#isis retransmit-throttle-interval <milliseconds>
where:
milliseconds is the minimum delay from 1 to 65535 milliseconds between LSP
retransmissions on the interface.
Setting the Designated Router Priority
A BSR uses hello packets to advertise its priority to become a designated router. IS-IS
uses the advertised priorities on all multiaccess networks to elect a designated router
for the network. This router is responsible for sending network LSP advertisements,
which describe all the routers attached to the network. These advertisements are
flooded throughout a single area. The priority value is meaningful only on a
multiaccess network. It has no meaning on a point-to-point interface.
Note: The number of seconds should be greater than the expected round-trip
delay between any two routers on the attached network. Set this parameter
conservatively to avoid unnecessary retransmission. Increase the number of
seconds for networks that have serial lines and virtual links.
