Abstract
A method in an active network element. The network element is coupled with a standby network element by an inter-chassis communication channel used to synchronize session state for sessions handled by the active network element from the active network element to the standby network element. The network element is deployed in a Layer 3 network that is used to transmit Layer 2 data. The method is one of limiting disruption in the handling of the sessions. The method includes monitoring a Layer 2 interface for failures and monitoring a Layer 3 interface for failures. A failure is detected on the Layer 2 interface. The network element communicates with the standby network element, over the inter-chassis communication channel, in response to detecting the failure on the Layer 2 interface, to have the standby network element at least assist with the handling of the sessions.
