To configure a new sequence of statements for an existing route map, specify the same route map name
but use a different sequence number. For example, the following commands create a new sequence 20 for
the rm_1 route map:
-> ip route-map rm_1 sequence-number 20 action permit
-> ip route-map rm_1 sequence-number 20 match ipv4-interface to-finance
-> ip route-map rm_1 sequence-number 20 set metric 5
The resulting route map appears as follows:
-> show ip route-map rm_1
Route Map: rm_1 Sequence Number: 10 Action permit
match tag 8
set metric 1
Route Map: rm_1 Sequence Number: 20 Action permit
match ip4 interface to-finance
set metric 5
Sequence 10 and sequence 20 are both linked to route map rm_1 and are processed in ascending order
according to their sequence number value. Note that there is an implied logical OR between sequences. As
a result, if there is no match for the tag value in sequence 10, then the match interface statement in
sequence 20 is processed. However, if a route matches the tag 8 value, then sequence 20 is not used. The
set statement for whichever sequence was matched is applied.
A route map sequence can contain multiple match statements. If these statements are of the same kind
(e.g., match tag 5, match tag 8, etc.) then a logical OR is implied between each like statement. If the match
statements specify different types of matches (e.g. match tag 5, match ip4 interface to-finance, etc.), then a
logical AND is implied between each statement. For example, the following route map sequence
redistributes a route if its tag is either 8 or 5:
-> ip route-map rm_1 sequence-number 10 action permit
-> ip route-map rm_1 sequence-number 10 match tag 5
-> ip route-map rm_1 sequence-number 10 match tag 8
The following route map sequence redistributes a route if the route has a tag of 8 or 5 and the route was
learned on the IPv4 interface to-finance:
-> ip route-map rm_1 sequence-number 10 action permit
-> ip route-map rm_1 sequence-number 10 match tag 5
-> ip route-map rm_1 sequence-number 10 match tag 8
-> ip route-map rm_1 sequence-number 10 match ipv4-interface to-finance
Configuring Access Lists
An IP access list provides a convenient way to add multiple IPv4 or IPv6 addresses to a route map. Using
an access list avoids having to enter a separate route map statement for each individual IP address. Instead,
a single statement is used that specifies the access list name. The route map is then applied to all the
addresses contained within the access list.
Configuring an IP access list involves two steps: creating the access list and adding IP addresses to the list.
To create an IP access list, use the
and specify a name to associate with the list. For example,
-> ip access-list ipaddr
-> ipv6 access-list ip6addr
