Could someone from Cogent contact me off-list? We are having an issue with=
one of our downstream customers who is multi-homed to another carrier. Th=
e end customer is advertising their prefix to both us and the other carrier=
. Both us and the other carrier peer with 174. However, if the prefix is =
preferred through us and the outbound traffic flows over the other carrier =
it is dropped. We suspect uRPF-strict on the other carriers Cogent link. =
We are working together with the other carrier and have a ticket open the =
help desk seem to be confused. Any help would be appreciated. Thanks
