Filter-based forwarding enables you to configure packet filters that classify packets based on header information, such as IP source address, IP destination address, IP protocol field, source and destination TCP/UDP port numbers. If a packet matches the conditions of the filter, then traditional destination-based forwarding occurs using the routing table that is specified in the accept action of the filter definition language. Filter-based forwarding provides a very simple yet powerful tool: a policy-based routing table selector.
Filter-based forwarding allows you to control the next-hop selection for customer traffic by defining a packet filter that examines the fields in a packet's header. If a packet satisfies the match conditions of the filter, the packet is forwarded using the routing table instance specified in the filter action statement.
