Release Information

Statement introduced before JUNOS Release 7.4.

Support for configuration in the dynamic database introduced in JUNOS Release 9.5.

Description

Define a routing policy, including subroutine policies.

Options

actions—(Optional) One or more actions to take if the conditions match. The actions are described in Configuring Actions in Routing Policy Terms and Configuring Actions in Routing Policy Terms.
family family-name—(Optional) Specify an address family protocol. Specify inet for an IPv4 address protocol. Specify inet6 for a 128-bit IPv6 address protocol, and to enable interpretation of IPv6 router filter addresses. When family is not specified, the router uses the default IPv4 setting.
from—(Optional) Match a route based on its source address.
match-conditions—(Optional in from statement; required in to statement) One or more conditions to use to make a match. The qualifiers are described in Configuring Match Conditions in Routing Policy Terms.
policy subroutine-policy-name—Use another policy as a match condition within this policy. The name identifying the subroutine policy can contain letters, numbers, and hyphens (-) and can be up to 255 characters long. To include spaces in the name, enclose it in quotation marks (“ ”). For information about how to configure subroutines, see Configuring Subroutines in Routing Policy Match Conditions.
policy-name—Name that identifies the policy. The name can contain letters, numbers, and hyphens (-) and can be up to 255 characters long. To include spaces in the name, enclose it in quotation marks (“ ”).
prefix-list prefix-list-name —Name of a list of IPv4 or IPv6 prefixes. To create a named list of IP address prefixes, see Extended Match Conditions Configuration.
prefix-list-filter prefix-list-name—Name of a prefix list to evaluate using qualifiers; match-type is the type of match (see Configuring Route Lists for Use in Routing Policy Match Conditions), and actions is the action to take if the prefixes match.
route-filter destination-prefix match-type <actions>—(Optional) List of routes on which to perform an immediate match; destination-prefix is the IPv4 or IPv6 route prefix to match, match-type is the type of match (see Configuring Prefix Lists for Use in Routing Policy Match Conditions), and actions is the action to take if the destination-prefix matches.
source-address-filter source-prefix match-type <actions>—(Optional) Unicast source addresses in multiprotocol BGP (MBGP) and Multicast Source Discovery Protocol (MSDP) environments on which to perform an immediate match. source-prefix is the IPv4 or IPv6 route prefix to match, match-type is the type of match (see Configuring Route Lists for Use in Routing Policy Match Conditions), and actions is the action to take if the source-prefix matches.
term term-name—Name that identifies the term.
to—(Optional) Match a route based on its destination address or the protocols into which the route is being advertised.
then—(Optional) Actions to take on matching routes. The actions are described in Configuring Actions in Routing Policy Terms and Configuring Actions in Routing Policy Terms.

Usage Guidelines

See Defining Routing Policies, Extended Match Conditions Configuration and Configuring Dynamic Routing Policies.

Note: We recommend that you use the dynamic database with caution because it is not subject to the same verification required by the commit process for the standard configuration database.

Required Privilege Level
