Tom,

Can you please elaborate how the outbound filter with the community tag of
no-export would help... as I'm still not too clear what it will achieve.

And sorry for the stupid question...

Thanks again.

Hunt,

You are correct, there is nothing filtering the routes entering from
Router B, without local preference set higher on 10.1.1.1 (Router A?) for
the routes, nothing will prevent AS 202 from being used for other
destinations as well.

More confusing to me is the configuration.

I read the question as if Router B should only be used for packets
_originating_ from AS 202, which should use the T1 connection.  In this
case an outbound filter would be appropriate, along with a community tag
of no-export.

Even if this the reverse is true (which the configuration seems to
indicate), the as-path access-list is only setting local preference for
the AS 300 destination!  It seems like the following access-list should
have been used:

  ip as-path access-list 1 permit ^202$

Then again, perhaps I have just totally misunderstood the question. Either
way, I hope that this helps.

- Tom
