Route Map Examples

Requirements:

1. Redistribute interface route for eth3 into OSPF.

2. Set the OSPF route-type to AS type-2 with cost 20.

Syntax:

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

Requirements:

1. Do not accept routes from RIP neighbor 192.0.2.3.

2. Accept routes from neighbor 192.0.2.4 as is.

3. For all other routes increment the metric by 2.

Syntax:

set routemap rip-in id 10 onset 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

Requirements:

1. Redistribute all static routes into BGP AS group 400.

2. Set the MED value to 100.

3. Prepend the AS number to the aspath 4 times.

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

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

Syntax:

set routemap static-to-bgp id 10 onset 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
