Defining Route Maps
Route maps are used when redistributing routes into an OSPF, RIP, or EIGRP routing process. They are
also used when generating a default route into an OSPF routing process. A route map defines which of
the routes from the specified routing protocol are allowed to be redistributed into the target routing
process.
To define a route map, perform the following steps:
To create a route map entry, enter the following command:
Step 1
hostname(config)# route-map name {permit | deny} [ sequence_number ]
Route map entries are read in order. You can identify the order using the sequence_number option, or
the security appliance uses the order in which you add the entries.
Enter one or more match commands:

hostname(config-if)# exit
You must use the setroute argument with the ip address dhcp command to obtain the default route
using DHCP. Make sure the administrative distance is greater than the administrative distance of the
tracked route.
To use a default route obtained through PPPoE, enter the following commands:
hostname(config)# interface phy_if
hostname(config-if)# pppoe client route track track_id
hostname(config-if)# pppoe client route distance admin_distance
hostname(config-if)# ip addresss pppoe setroute
hostname(config-if)# exit
You must use the setroute argument with the ip address pppoe command to obtain the default route
using PPPoE. Make sure the administrative distance is greater than the administrative distance of
the tracked route.
To match any routes that have a destination network that matches a standard ACL, enter the
following command:
hostname(config-route-map)# match ip address acl_id [ acl_id ] [...]
If you specify more than one ACL, then the route can match any of the ACLs.
To match any routes that have a specified metric, enter the following command:
hostname(config-route-map)# match metric metric_value
The metric_value can be from 0 to 4294967295.
To match any routes that have a next hop router address that matches a standard ACL, enter the
following command:
hostname(config-route-map)# match ip next-hop acl_id [ acl_id ] [...]
If you specify more than one ACL, then the route can match any of the ACLs.
To match any routes with the specified next hop interface, enter the following command:
hostname(config-route-map)# match interface if_name
