Abstract:
1. A method, comprising: receiving a packet from a first network device to a second network device, wherein the first and second network devices are connected to form a link, the first network device and the second network device each having a version of a routing protocol, the packet identifying the first network device's routing protocol version; determining whether the first network device's routing protocol version is the same as the second network device's routing protocol version; verifying the first network device's routing protocol version as being the same as the second network device's routing protocol version; choosing the same routing protocol version acceptable to the first and second network devices; and configuring the link such that the routing protocol version is the same for the first and second network devices, wherein the version of the routing protocol of each network device is one of a triggered type or a periodic type, and the method further comprises detecting the first network device's routing protocol type, and determining whether the first network device's routing protocol type is the same as the second network device's routing protocol type.
