6.15 PBR Congiuration
6.15.1 PBR Description
This section descripe how to configure PBR. PBR is the abbrecation of Policy Based Routing. PBR
make the user have the ability to route ip packet according some policy other than dynamic routing
protocol. We currently support the following policy: based on the length of ip packet, source ip address.
You can set gateway or outgoing interface for packets matching the policy. PBR can support load
balance.
The rule for PBR selecting nexthop is following ：
(1) If set ip next-hop is configured,and the gateway is reachble,the gateway will be used. If multiple
gateway is configured, use the first reachable gateway，if load-balance key word is used，the
load balance is used between these gateways。
(2) If set interface is configured, and the outgoing interface is routabale(interface protocol up， and ip
address is confured)，use the outgoing interface。If multiple outgoing interfaces are configured,
first routable interface will be used. If load-balance key word is used，the load balance is used
between these interface。If both set ip next-hop and set interface configured, ，use set ip
next-hop first.
(3) Set ip default next-hop or set default interface won't be used untill routing lookup failed.
6.15.2 PBR Configuration Task List
If you want to use PBR，the following configuration is needed:
♦ Create standard access-list(optional)
♦ Create route-map
♦ Apply route-map on interface
6.15.3 create standard access-list
To create access-list, following the step bellow
command
