Abstract

See full text

Exemplary methods in a first network device of an inter-chassis redundancy (ICR) system communicatively coupled to a second network device of the ICR system, the first network device configured as an active ICR device communicatively coupled to a third network device via a first link and a third link, the second network device configured as a standby ICR device, wherein the first link and the second link belong to a first multi-chassis link aggregation group (MC-LAG), include negotiating with a first client device to create a first session that is carried over the first link of the first MC-LAG, determining whether the first session is stateful, wherein a session is stateful if it is carried over an MC-LAG, and in response to determining the first session is stateful, sending session information associated with the first session to the second network device.
