Configuring if-match clauses
Follow these guidelines when you configure if-match clauses:
• The if-match clauses of a routing policy node have a logical AND relationship. A route must satisfy
all if-match clauses before it can be handled by the apply clauses of the node. If an if-match
command exceeds the maximum length, multiple identical if-match clauses are generated. These
clauses have a logical OR relationship. A route only needs to match one of them.
• You can specify no or multiple if-match clauses for a routing policy node. If no if-match clause is
specified for a permit-mode node, all routing information can pass the node. If no if-match clause
is specified for a deny-mode node, no routing information can pass the node.
• If the ACL referenced by an if-match clause does not exist, the clause is always satisfied; if no rules
of the referenced ACL are matched or the matching rule is inactive, the clause is not satisfied.
• An ACL specified in an if-match clause must be a non-VPN ACL.
• The if-match command for matching IPv4 destination, next hop, and source is different from the
if-match command for matching IPv6 ones.
• BGP does not support criteria for matching against outbound interfaces of routing information.

3. Define match criteria for IPv4 routes.
• Match IPv4 routing information
specified in the ACL:
if-match acl acl-number
• Match IPv4 routing information
specified in the IP prefix list:
if-match ip-prefix ip-prefix-name
• Match IPv4 routing information whose
next hop or source is specified in the
ACL or IP prefix list:
if-match ip { next-hop | route-source }
{ acl acl-number | ip-prefix
ip-prefix-name }
Optional.
Not configured by
default.
4. Match IPv6 routing information whose
next hop or source is specified in the
ACL or IP prefix list.
if-match ipv6 { address | next-hop |
route-source } { acl acl-number |
prefix-list ipv6-prefix-name }
Optional.
Not configured by
default.
5. Match BGP routing information whose
AS_PATH attribute is specified in the
AS path lists.
if-match as-path
AS-PATH-number&<1-16>
Optional.
Not configured by
default.
