Abstract
Multicast traffic may be routed using DVMRP or PIM over a Split MultiLink Trunk (SMLT). Network elements on the split side of the SMLT are interconnected by an Inter-Switch Trunk (IST) to enable them to exchange control messages associated with the multicast. When a control message is received on the IST, the network element will determine if the multicast control message is associated with a normal multicast or is associated with multicast over an SMLT link. Control messages related to SMLT links will be processed as if they were received over the SMLT link rather than the IST link. To prevent traffic from being forwarded by multiple network elements over the SMLT link, data traffic from an IST link may not be transmitted over an SMLT link. Flags are used to indicate whether a link is a SMLT link or regular link. Fast recovery may occur by causing participants to transmit triggered join messages upon recovery from a failure.
