Chapter 27 IPv6 PBR Configuration
27.1 Introduction to PBR (Policy-based Router)
Policy-based routing provides a more powerful control over the forwarding and store of
messages than traditional routing protocol to network managers. Traditionally, routers use the
routing table derived from router protocol, and forward according to destination addresses.
The policy-based router is more powerful and more flexible than the traditional one, because it
enables network managers to choose the forwarding route not only according to destination
addresses but also the size of messages, or source IP addresses. Policy can be defined as
according to the balance of load in multiple routers or according to the quality of service (QOS)
of the total flow forwarded in each line.
PBR (Policy-Based Routing) is a method which politically specifies the next hop when
forwarding a data packet according to the source address, destination address, IP priority,
TOS value, IP protocol, source port, destination port and other information of an IP packet.
