And, don't forget that you even can do multihoming without PI address space, by multihoming of PA assigment (if LIR permitted it).
Multihoming, but not backups. Because of some traffic will flow through [aggregated] LIR route if even link with LIR will be damaged. It is very some traffic. Some traffic flows on default gateway, even if you have BGP full view on

If your multihomed prefix doesn't exist in some part of Internet, you may have troubles with connectivity with this part of Internet, don't looking PA or PI addresses you uses. In the case of PA specific, traffic from this part of Internet will flow to aggregated route, and, if specific route would be found on next hops, will go to specific route from this next hops. In the case of PI, traffic will flow to default or will be dropped. Anyway, if your prefix doesn't routed anywhere, it isn't normal situation, don't depend of addresses u use. -- Regards, Gennady Abramov, CCNP, AGV77-RIPE Demos-Internet NOC Phone: +7 (495) 737-0436 http://www.demos.ru/address
