Abstract:
A method of routing data in a network includes sending an instruction to a router to statically route outbound traffic to a firewall farm having an anycast address, identifying prefixes of endpoints that communicate with router, instructing a firewall router to send a route advertisement to the network announcing that the firewall router is the subsequent best hop for data bound for the endpoints, detecting a change in network condition, and sending another instruction to the router to route outbound traffic to another firewall farm having the anycast address after detecting the change.
