ip as-path!!!


There's something we don't get. If we try some filtering with a simple acess-list and IP prefixes everything works as expected. Now if we simply replace the lines access-list with ip as-path access list, it simply denies everything, even if we have a permit any..... HELP!

you can do one of the following:
1) implement the filter by using a route map: we know that in this case it works;
2) use "permit .*" instead of "permit any" (solution not yet tested).

In any case, you can come this afternoon at the session from 16.00 to 18.00, so that we can have a look at the problem.

Thanks, actually the .* doens't work either. We have tried for too much time now, .* and any for a strange reason seems to deny everything!

We changed our policy and decided to forward to R1 only information originated from AS 65021 in the last question of 3.3 This works fine.

Have a nice afternoon.
