Hi,In my case, I have 6453 and 174 for transit. I want to get to 577 which is directly connected to 6453 and 174. 577 has a higher local pref on paths via 174. Short of shutting my 174 session (or some deaggregation), I dont have a way to influence how 577 gets back to me. I can easily exit out 6453, but it does nothing for the return packets. I have enough capacity on 6453 to handle all my traffic, but its a Draconian step to take and some traffic via 174 is fine and would be worse if I fully shut the session. (ie. peers of 174 in Toronto)
