Configuring RLM
The goal of Redundant Link Manager (RLM) is to primarily provide a virtual link management over
multiple IP networks so that the Q.931 signaling protocol and other proprietary protocols can be
transported on top of multiple redundant links between the Cisco signaling controller and the access
server.
We recommend that all access servers should use at least two IP interfaces to connect to the primary
and alternative IP interfaces of the signaling controller. Otherwise, the control traffic will be
impacted by the data traffic by sharing the same interface for both types of traffic.
