Configuring IS-IS Configuring IS-IS

tributed into the IS-IS network. All other routes with a different metric value are dropped.
To modify route information before it is redistributed, use the ip route-map command with a set
parameter. For example,
-> ip route-map rip-to-isis sequence-number 10 set metric 5
The above command configures a set statement for the rip-to-isis route map that changes the metric value
to five. Because this statement is part of the rip-to-isis route map, it is only applied to routes that have an
existing metric value equal to eight.
The following is a summary of the commands used in the above examples:
-> ip route-map rip-to-isis sequence-number 10 action permit
-> ip route-map rip-to-isis sequence-number 10 match metric 8
-> ip route-map rip-to-isis sequence-number 10 set metric 5
To verify a route map configuration, use the show ip route-map command:
-> show ip route-map
Route Maps: configured: 1 max: 200
Route Map: rip-to-isis Sequence Number: 10 Action permit
match metric 8
set metric 5
Deleting a Route Map
Use the no form of the ip route-map command to delete an entire route map, a route map sequence, or a
specific statement within a sequence.
To delete an entire route map, enter no ip route-map followed by the route map name. For example, the
following command deletes the entire route map named rip-to-isis:
-> no ip route-map rip-to-isis
To delete a specific sequence number within a route map, enter no ip route-map followed by the route
map name, then sequence-number followed by the actual number. For example, the following command
deletes sequence 10 from the rip-to-isis route map:
-> no ip route-map rip-to-isis sequence-number 10
Note that in the above example, the rip-to-isis route map is not deleted. Only those statements associated
with sequence 10 are removed from the route map.
To delete a specific statement within a route map, enter no ip route-map followed by the route map name,
then sequence-number followed by the sequence number for the statement, then either match or set and
the match or set parameter and value. For example, the following command deletes only the match metric
8 statement from route map rip-to-isis sequence 10:
-> no ip route-map rip-to-isis sequence-number 10 match metric 8
Note. Configuring match statement is not required. However, if a route map does not contain any match
statement and the route map is applied using the ip redist command, the router redistributes all routes into
the network of the receiving protocol.
