Table 10: Routing Policy Match Conditions (continued)
Match Condition
Match
Condition
Category
from Statement Description
to Statement Description
route-type value
Standard
Type of route. The value can be one of the following:
• external—External route.
• internal—Internal route.
source-address-filter
destination-prefix
match-type
Extended
List of multicast source addresses. When
specifying a source address, you can
specify an exact match with a specific
route or a less precise match using match
types. You can configure either a common
action that applies to the entire list or an
action associated with each prefix. For
more information, see “Configuring Route
Lists for Use in Routing Policy Match
Conditions” on page 119.
You cannot specify this match condition.
state (active |
inactive)
Standard
(BGP export only) Match on the following types of advertised routes:
• active—An active BGP route
• inactive—A route advertised to internal BGP peers as the best external path even
if the best path is an internal route
• inactive—A route advertised by BGP as the best route even if the routing table did
not select it to be an active route
tag string tag2 string
Standard
Tag value. You can specify two tag strings: tag (for the first string) and tag2. These
values are local to the router and can be set on configured routes or by using an import
routing policy.
You can specify multiple tags under one match condition by including the tags within
a bracketed list. For example: from tag [ tag1 tag2 tag3 ];
For OSPF and IS-IS, the tag match conditions match the 32-bit tag field in external
link-state advertisement (LSA) packets.
Configuring Actions in Routing Policy Terms
Each term in a routing policy can include a then statement, which defines the actions to
take if a route matches all the conditions in the from and to statements in the term:
then {
actions;
}
You can include this statement at the following hierarchy levels:
• [edit policy-options policy-statement policy-name term term-name]
• [edit logical-systems logical-system-name policy-options policy-statement policy-name
term term-name]
