In a real world scenario, I bumped into Verio's RPF peer filters yesterday.
Due to the large outage at 200 paul, the /19 that one of my /24's is out of went away. Obviously due to prefix filtering policies, verio didn't have my /24. I had several people complain who were multihomed, and did have the /24 from their other carrier(s). Unfortunately, my best path to these customers was via verio, who's rpf promptly blocked my return traffic :(
Speaking about this specific issue, since there was no return path in our RIB/FIB, we dropped the packets, yes. If you were annoucing the /19 or something that fit our filtering policy (in your alternate locations) you would not have had issues. - Jared -- Jared Mauch | pgp key available via finger from jared@puck.nether.net clue++; | http://puck.nether.net/~jared/ My statements are only mine.
