IOS-XR question

Ahmede

When I try to convert route map in IOS to RPL in IOS-XR, Cisco documenatation has this example..

ip prefix-list 101

10 permit 10.48.0.0/16 le 32

20 permit 172.48.0.0/19 le 32

30 permit 172.10.10.0/24

40 permit 172.11.1.0/24

50 permit 192.168.3.0/24

60 permit 192.168.8.0/21

70 permit 192.168.32.0/21

In IOS_XR it will be

prefix-set ps101

10.48.0.0/16 le 32

172.48.0.0/19 le 32

172.10.10.0/24

172.11.1.0/24

192.168.3.0/24

192.168.8.0/21

192.168.32.0/21

end-set

Now, in XR there's no permit or deny.. So if I have route map like this

ip prefix-list 101

10 permit 10.48.0.0/16 le 32

20 permit 172.48.0.0/19 le 32

30 permit 172.10.10.0/24

35 deny 172.11.1.5/32

40 permit 172.11.1.0/24

50 permit 192.168.3.0/24

60 permit 192.168.8.0/21

70 permit 192.168.32.0/21

How can we convert that? How to distinguish between the permit and the deny?

Ahmed,

You would configure the following prefix-set without the 172.11.1.5/32 as follow:

prefix-set ps 101

10.48.0.0/16 le 32

172.48.0.0/19 le 32

172.10.10.0/24

172.11.1.0/24

192.168.3.0/24

192.168.8.0/21

192.168.32.0/21

end-set

use it in the route-policy as follow:

if destination in ps101 then

set local-preference 100

endif

172.11.1.5/32 would not match the condition.
