What is the principle of route management of IPOS?
The route management of IPOS: (suppose there are M peers) one route obtained from each Peer should iterate on n IGP load balancing link and creates N routes. When M peers send the same BGP route, M×N load balancing forms. If M×N is larger than eight, IPOS will choose eight routes randomly. The routes advertised in FIB are not definite (4～6 indefinite; advertised routes in FIB are the same under different situation). Even if six links are advertised in FIB during cutover, the link is up/down in actual application. Once the link is up/down, IPOS choose the route again and re-advertises the route. It is possible that parts of link cannot be advertised in FIB table.
