492CHAPTER 32: CONFIGURING IP POLICY ROUTING

Creating a Routing The strategy specified with the strategy name may have several strategy points Policy and each strategy point is specified with sequence-num. The smaller the

sequence-num, the higher the preference and the defined strategy will be executed first. This strategy can be used to import routes and perform policy routing when IP messages are forwarded. When a routing policy is recreated, the configuration information of the new routing policy overwrites that of the old routing policy. The contents of the strategy is specified by if-match and apply clauses.

See “Configuring IP Routing Policy” for details.

Perform the following configurations in system view.

Table 568 Create a Routing Policy

Operation	Command
Create a routing policy and enter into the	route-policy policy-name{ permit
Routing policy view	deny} { seq-number }
Delete a routing policy	no route-policy policy-name[ permit
	deny ] [ seq-number]

permit means policy routing for the messages meets the conditions and deny means no policy routing for the message meets the conditions.

By default, no strategy is created.

Define Match Rules IP policy routing provides two if-match clauses that allow matching strategy according to IP message length and IP address. One strategy includes multiple if-match clauses, which can be used in combination.

Perform the following configurations in Routing policy view.

Table 569 Define Match Rules

Operation	Command
Specify IP message matching the length	if-match length min-lenmax-len
Remove IP message matching the length	no if-match length
Specify IP address matching the specified	if-match ip address acl-number
access lists
Remove IP address matching the specified	undo if-match ip address
access lists

By default, no if-match clause is defined.

Define Apply Clause IP policy routing provides 5 apply clauses. One strategy includes multiple apply clauses, which can be used in combination.

Perform the following configurations in Routing policy view.

Table 570 Define Apply Clause

Operation	Command
Set message precedence	apply ip	precedence precedence
