Abstract
A method implemented by a network device for selection of a routing table in a Policy Based Routing (PBR) system is described. The method may include receiving a packet from a first network domain; generating a firewall mark for the packet, wherein the firewall mark includes a network domain indication and a packet classification indication; determining a match between the network domain indication of the packet and a selector of a matched rule in a set of rules; and upon determining the match between the network domain indication of the packet and the selector of the matched rule, inputting the firewall mark to a function of the matched rule to identify a routing table for the packet.
