Route Maps - Examples

For more information, see sk100501: How to configure Routemaps in Gaia Clish.

Redistribute interface route for eth3 into OSPF, and set the OSPF route-type to AS type-2 with cost 20:

set routemap direct-to-ospf id 10 on

set routemap direct-to-ospf id 10 match interface eth3

set routemap direct-to-ospf id 10 match protocol direct

set routemap direct-to-ospf id 10 action route-type type-2

set routemap direct-to-ospf id 10 action metric value 20

set ospf export-routemap direct-to-ospf preference 1 on

Do not accept routes from RIP neighbor 192.0.2.3, accept routes from neighbor 192.0.2.4 as is, and for all other routes increment the metric by 2:

set routemap rip-in id 10 on

set routemap rip-in id 10 restrict

set routemap rip-in id 10 match neighbor 192.0.2.3

set routemap rip-in id 15 on

set routemap rip-in id 15 match neighbor 192.0.2.4

set routemap rip-in id 20 on

set routemap rip-in id 20 action metric add 2

set rip import-routemap rip-in preference 1 on

Redistribute all static routes into BGP AS group 400.

Set the MED value to 100, prepend our AS number to the aspath 4 times.

If the route belongs to the prefix 192.0.2.0/8, do not redistribute.

Send all BGP routes whose aspath matches the regular expression (100 200+) and set the MED value to 200.

set routemap static-to-bgp id 10 on

set routemap static-to-bgp id 10 restrict

set routemap static-to-bgp id 10 match protocol static

set routemap static-to-bgp id 10 match network 192.0.2.0/8 all

set routemap static-to-bgp id 15 on

set routemap static-to-bgp id 15 match protocol static

set routemap static-to-bgp id 15 action metric 100

set routemap static-to-bgp id 15 action aspath-prepend-count 4

set routemap bgp-out id 10 on

set routemap bgp-out id 10 match aspath-regex "(100 200+)" origin any

set routemap bgp-out id 10 action metric 200

set bgp external remote-as 400 export-routemap bgp-out preference 1 family inet on

set bgp external remote-as 400 export-routemap static-to-bgp preference 2 family inet on

Note - There is no need for a match protocol statement for routes belonging to the same protocol.

To redistribute OSPFv2 routes from one instance to a different instance.

This routemap ("Intranet") matches all OSPF routes from OSPF instance default in the prefix-list "Intranet" (only when used in OSPF because of missing match statement).

Match all static routes in prefix-list "Intranet".

Match all direct routes in prefix-list "Intranet".

Match all aggregate routes in prefix-list "Intranet".

Match all kernel routes in prefix-list "Intranet".

Export to OSPF - no need to match protocol OSPF for one of the IDs, it will assume it.

Do not match OSPF2 or OSPF2ASE, they are both matched implicitly for this ID.

set routemap Intranet id 1 on

set routemap Intranet id 1 allow

set routemap Intranet id 1 match ospf-instance default on

set routemap Intranet id 1 match prefix-list Intranet preference 1 on

set routemap Intranet id 11 on

set routemap Intranet id 11 match prefix-list Intranet preference 1 on

set routemap Intranet id 11 match protocol static

set routemap Intranet id 12 on

set routemap Intranet id 12 match prefix-list Intranet preference 1 on

set routemap Intranet id 12 match protocol direct

set routemap Intranet id 13 on

set routemap Intranet id 13 match prefix-list Intranet preference 1 on

set routemap Intranet id 13 match protocol aggregate

set routemap Intranet id 14 on

set routemap Intranet id 14 match prefix-list Intranet preference 1 on

set routemap Intranet id 14 match protocol kernel

Redistribute all OSPFv3 (internal and external) routes into BGP group 400.

Set the outgoing community string to 'no-export, 200 as 100'.

For BGP IPv6 routes, send them with an empty community string.

For all routes set the nexthop value to 3003::abcd:1012 (the address on the interface connecting to the peers).

Note - To exchange IPv6 routes in BGP the multiprotocol capability must be turned ON in BGP Configuration for the peer.

set routemap ospf3-to-bgp id 10 on

set routemap ospf3-to-bgp id 10 match protocol ospf3 #OSPF3 INTERNAL ROUTES

set routemap ospf3-to-bgp id 10 action community replace on

set routemap ospf3-to-bgp id 10 action community no-export on

set routemap ospf3-to-bgp id 10 action community 200 as 100 on

set routemap ospf3-to-bgp id 10 action nexthop ipv6 3003::abcd:1012

 

set routemap ospf3-to-bgp id 20 on

set routemap ospf3-to-bgp id 20 match protocol ospf3ase #FOR AS EXTERNAL ROUTES

set routemap ospf3-to-bgp id 20 action community replace on

set routemap ospf3-to-bgp id 20 action community no-export on

set routemap ospf3-to-bgp id 20 action community 200 as 100 on

set routemap ospf3-to-bgp id 10 action nexthop ipv6 3003::abcd:1012

 

set routemap bgp-out id 10 on

set routemap bgp-out id 10 action community replace on

set routemap bgp-out id 10 action community none on

set routemap ospf3-to-bgp id 10 action nexthop ipv6 3003::abcd:1012

 

set bgp external remote-as export-routemap bgp-out preference 1 family inet6 on

set bgp external remote-as export-routemap ospf3-to-bgp preference 2 family inet6 on

To redistribute routes from an OSPFv2 Instance to BGP:

set routemap OSPF-to-BGP id 10 on

set routemap OSPF-to-BGP id 10 allow

set routemap OSPF-to-BGP id 10 match ospf-instance 222 on

set routemap OSPF-to-BGP id 10 match protocol ospf2

To redistribute routes from an OSPFv3 Instance to BGP:

set routemap OSPF-to-BGP id 10 on

set routemap OSPF-to-BGP id 10 allow

set routemap OSPF-to-BGP id 10 match ospf-instance 222 on

set routemap OSPF-to-BGP id 10 match protocol ospf3
