RSMLT

In many cases, core network convergence time depends on the length of time a routing protocol requires to successfully converge. Depending on the specific routing protocol, this convergence time can cause network interruptions that range from seconds to minutes.

Routed Split MultiLink Trunking (RSMLT) permits rapid failover for core topologies by providing an active-active router concept to core SMLT networks.

RSMLT scenarios include SMLT triangles, squares, and SMLT full-mesh topologies, with routing enabled on the core VLANs.

Routing protocols include the following:

In the event of core router failures, RSMLT manages packet forwarding, thus eliminating dropped packets during the routing protocol convergence.
