摘要： The present invention permits translation of SM addresses (*, G1) and (*, G2) to configurable SSM addresses (S0, G0). IGMPv2 group membership queries from the receiver subnet are translated to IGMPv3 membership queries for processing in a SSM network. In the preferred embodiment, packets travel via a connection to the multicast router (mrouter). The mrouter queries an IGMPv2 receiver. The IGMPv2 receiver generates a membership report and sends it back to the mrouter. The mrouter translates the membership report into a (S0, G0) as specified in a multicast address translation table and stores the translation in the Multicast Forward Information Base (MFIB) located in the mrouter. Multicast payload addressed (S0, G0) flowing towards the IGMPv2 receiver can be translated to (S0, G0). When media data is addressed to (S0, G0), the mrouter consults the MFIB for forwarding and can also translate the destination address to (S1, G1).

摘要： A method of router interface level 2 redundancy, and router implementing the method, including one or more of the following: starting redundant ports that are members of a level 2 redundancy group (L2RG) in a DOWN state; determining that none of the redundant ports are in an ACTIVE state; switching a first one of the redundant ports to an ACTIVE state; activating an Internet protocol interface for the L2RG; inserting an Internet protocol route for an interface subnet in an FIB of a router that contains the redundant ports; binding the Internet protocol route for the interface to the first one of the redundant ports; transitioning the first one of the redundant ports to a DOWN state; transitioning the Internet protocol interface to the DOWN state from an UP state; and removing the Internet protocol route for the interface from the FIB of the router.

摘要： A method and system for STP-aware subscriber management is disclosed for managing redundant access ports. The STP-aware system includes Access Loop Pairs which provide continuity of subscriber management information in the event of an access port failure. The STP-aware subscriber management system is particularly useful for overcoming the requirements for extra ports within Link Access Group configured access networks known in the art.

摘要： 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.
