Quite a few times it has been mentioned to me that some peering agreements require support for the IPv4 source routing options. I was wondering whether this is still the case for some ISPs, or it is not the case anymore.
Before we decommissioned our last open peering fabric, source-routing was important to make sure your peer wasn't pointing default (or similar) to you. With the advent of private (and far more limited) bilateral peering as a preference to fabric based peering (at least among the ones who set peering policies globally) this has become less of an issue. RFC 5095 aside. Deepak
