Bridge/router and method for avoiding packet replication during a failure in a network
Abstract:
A bridge/router and method are described herein that are capable of avoiding packet replication at layer 2 where there is a failure in a network. In one embodiment, the bridge/router is informed about a fault which occurred within the network. Then, the bridge/router makes a determination about whether or not multiple LSPs would be used to flood/carry the same IP traffic out off a single port. If yes, the first bridge/router chooses one of the LSPs to carry the IP traffic out the single port and then prevents the IP traffic from being carried on the remaining LSP(s) out the single port which avoids the packet replication on a link which is associated with the single port. If no, then the first bridge/router allows the IP traffic to be carried on the LSPs out off more than one port.
