Chapter 9 Configuring IS-IS
Configuring IS-IS
You can use the following optional command in router address configuration mode:
You can use the following optional commands in interface configuration mode to tune IS-IS:
spf-interval [level-1 | level-2]
spf-max-wait [spf-initial-wait
spf-second-wait]
Example:
switch(config-router)# spf-interval
level-2 500 500 500
Configures the interval between LSA arrivals. The
optional parameters are as follows:
• lsp-max-wait—The maximum wait between
the trigger and SPF computation. The range is
from 500 to 65535 milliseconds.
• lsp-initial-wait—The initial wait between the
trigger and SPF computation. The range is
from 50 to 65535 milliseconds.
• lsp-second-wait—The second wait used for
SPF computation during backoff. The range is
from 50 to 65535 milliseconds.
Command Purpose
Command Purpose
adjacency-check
Example:
switch(config-router-af)# adjacency-check
Performs and adjacency check to verify that an
IS-IS instance forms an adjacency only with a
remote IS-IS entity that supports the same address
family. Enabled by default.
Command Purpose
isis csnp-interval seconds [level-1 |
level-2]
Example:
switch(config-if)# isis csnp-interval 20
Sets the Complete sequence number PDU (CNSP)
interval in seconds for IS-IS. The range is from 1 to
65535. The default is 10.
isis hello-interval seconds [level-1 |
level-2]
Example:
switch(config-if)# isis hello-interval 20
Sets the hello interval in seconds for IS-IS. The
range is from 1 to 65535. The default is 10.
isis hello-multiplier num [level-1 |
level-2]
Example:
switch(config-if)# isis hello-multiplier
20
Specifies the number of IS-IS hello packets that a
neighbor must miss before the router tears down an
adjacency. The range is from 3 to 1000. The default
is 3.
isis lsp-interval milliseconds
Example:
switch(config-if)# isis lsp-interval 20
Sets the interval in milliseconds between LSPs sent
on this interface during flooding. The range is from
10 to 65535. The default is 33.
