Abstract

Devices and methods are provided for exchanging route type capabilities between peer network devices, for example, Border Gateway Protocol (BGP) speakers, to prevent a BGP session reset when a particular route type is not supported by one of the peer network devices. A network device, that supports a set of route types, receives an announcing message indicating a route type capability of a peer network device. The network device selects a subset of route types supported by the peer network device from the set of route types based on the route type capability of the peer network device. The network device transmits an update message that advertises the subset of route types to the peer network device. Thus, a route type supported by the network device is not included in the update message if the route type is not advertised in the announcing message by the peer network device.
