How does one announce the same net (with the same origin AS) from different places on the Internet? Or should the "anycast" networks be announced from different origin AS:es? (Can't find "anycast" setup in my BGP for Dummies<tm>) ---------------------------------------- AS12345 IGP (announces net 1.2.3/24 among others) Connected to several major networks (P, Q, W, Z) ---------------------------------------- Isolated* site 1 (one unique routable net and 1.2.3/24) Router connected to a major network X, announced as AS12345 ---------------------------------------- Isolated* site 2 (one unique routable net and 1.2.3/24) Router connected to a major network Y, announced as AS12345 ---------------------------------------- * Isolated - No contact to main AS via IGP, tunnels or telepathy So when communicating among the sites (doing zone transfers etc) I use the unique routable network... piece of ca... ...but won't my BGP routers at the different locations be a bit puzzled when they see the announcements from another AS12345 for my unique networks (and more so for the anycast)? The config above does seem to break the concept of an AS.
