Abstract:
1. A method of routing data in an anycast network, the method comprising: sending an instruction from an intelligent route reflector device to an anycast router associated with the anycast network, wherein the instruction signals the anycast router to statically route outbound traffic related to a network service to an initial service node associated with an anycast address; identifying prefixes of internet protocol addresses of customer endpoints that communicate with the anycast network via the anycast router; instructing a service node router to send a route advertisement to the anycast network announcing that the service node router is a subsequent best hop for data traffic that is related to the network service and that is bound for customer endpoints having an internet protocol address that includes the prefixes; detecting a change in a network condition; and sending another instruction from the intelligent route reflector to the anycast router after detecting the change, wherein the other instruction signals the anycast router to route outbound traffic related to the network service to another service node associated with the anycast address.
