Hi All.
 
I'm studying for ccnp routing and I'm stuck on the simple IPv4 redistribution video, I've got through the video several times and still i can't get the filtering working through the Route-map and the prefix.
 
Does anybody have the config from the video that I can check my config against.
 
Thanks
chris

Hello Chris,

First of all, what video are you referring to in your post?
Secondly, do you mean filtering using route tags? I.e to prevent routes from goin into where it was originated?

Kindly give a clearer view of your challenge.

Goodluck with your preparations.

Cheers,
Alex

Try it this way.
Let`s assume that we want to allow only /24 networks to be redistributed.

1) create a prefix-list

ip prefix-list no_less_than_24 seq 5 permit 0.0.0.0/0 ge 24 le 24

2) create a route-map

route-map redist permit 10
match ip address prefix-list no_less_than_24

3) redistribute using this route-map

router ospf 1
redistribute connected subnets route-map redist

That`s it. Only /24 connected networks will be redistributed.
