If someone announce that network BGP and you announce it from your main router would your announcement will be "more dominant" and the network will return to UCSD back ? if the answer us yes maybe this is the way to stop someone from hijacking our network
Ronen, That is what they call AnyCast basically. It's also ok to announce the same space from different AS's as well. When you have multiple announcements of the same block. Who ever has the shortest AS path is who you will get routed to generally. The only way to guarantee a route path win is to announce something more specific like {44.68.52.0/25, 44.68.52.128/25}, but most carriers will not accept or announce anything smaller then a /24 so that most likely will not work in this case. Correct action here is to go down the path to have them withdraw the announcement or have their carriers block it from them.
