Route Map Redistribution Example
The following example configures the redistribution of OSPF routes into a BGP network using a route
map (ospf-to-bgp) to filter specific routes:
-> ip route-map ospf-to-bgp sequence-number 10 action deny
-> ip route-map ospf-to-bgp sequence-number 10 match tag 5
-> ip route-map ospf-to-bgp sequence-number 10 match route-type external type2
-> ip route-map ospf-to-bgp sequence-number 20 action permit
-> ip route-map ospf-to-bgp sequence-number 20 match ipv4-interface intf_ospf
-> ip route-map ospf-to-bgp sequence-number 20 set metric 255
-> ip route-map ospf-to-bgp sequence-number 30 action permit
-> ip route-map ospf-to-bgp sequence-number 30 set tag 8
-> ip redist ospf into bgp route-map ospf-to-bgp
The resulting ospf-to-bgp route map redistribution configuration does the following:
•
Denies the redistribution of Type 2 external OSPF routes with a tag set to five.
•
Redistributes into BGP all routes learned on the intf_ospf interface and sets the metric for such routes
to 255.
•
Redistributes into BGP all other routes (those not processed by sequence 10 or 20) and sets the tag for
such routes to eight.
