1. IPX Server Figure 1 6 IPX Multipath Routing Equal Least Cost Routes Because of the round robin algorithm IPX packets that belong to the same data stream may require resequencing at their ultimate destination Therefore higher layer protocols such as SPX must be used in both source and destination IPX routers to provide packet resequencing To derive maximum benefit from this feature the source and destination nodes should support burst mode operation Load Redistribution and Rerouting If the router with multipath enabled detects a failure it temporarily redistributes the IPX traffic among the remaining active original least cost routes When the router learns through RIP packets of the existence of an alternative least cost route or when the failed route returns IPX multipath returns to its original IPX traffic distribution 1 24 IPX Overview Multipath Route Precedence Priority The multipath mechanism generally uses the best path first However when two equal cost paths exist multipath uses the following priority scheme for route selection 1 Routes learned via RIP 2 Statically configured routes 3 Direct routes paths to other routers on a segment directly attached to the local router Multipath Configurations You can establish equal cost multipath routes over LAN or WAN segments to support IPX tra
