Abstract
Techniques are described for configuration of a multi-chassis router for managing periodic communications between the multi-chassis router and other network devices. The multi-chassis router selectively processes data received from a network by determine whether the data: (1) indicates an operational state of a network device in association with a routing protocol, or (2) conveys routing information for the routing protocol. Data conveying routing information are processed by a master routing component of the multi-chassis router, while data indicating an operational state of a network device are processed by one or more slave routing components of the multi-chassis router. The techniques also allow the multi-chassis router to allocate responsibility for managing periodic communications for the set of routing protocols among a plurality of hierarchically arranged cooperative routing components within the multi-chassis router, such as switch card chassis, line card chassis, or interface cards within each line card chassis.
