Table 11 Relationship between the match mode and the clauses
If a packet…
Then…
In permit mode
In deny mode
Matches an if-match clause on the
policy node
The apply clause is executed, and
the packet will not go to the next
policy node for a match.
The apply clause is not executed,
the packets will not go to the next
policy node for a match, and will
be forwarded according to the
routing table.
Fails to match an if-match clause
on the policy node
The apply clause is not executed,
and the packet will go to the next
policy node for a match.
The apply clause is not executed,
and the packet will go to the next
policy node for a match.
If a policy has a node with no if-match clause configured, all packets can pass the policy node. However,
an action is taken according to the match mode, and the packets will not go to the next policy node for
a match.
If a policy has a node with the permit match mode but no apply clause configured, all packets matching
an if-match clause can pass the policy node, and no action is taken; the packets will not go to the next
policy node for a match, and will be forwarded according to the routing table.
If a policy has a node with no if-match or apply clauses configured, all packets can pass the policy node,
and no action is taken; the packets will not go to the next policy node for a match, and will be forwarded
according to the routing table.
The nodes of a policy are in an OR relationship. If a packet matches a node, it passes the policy; if the
packet does not match any node of the policy, it fails to pass the policy and is forwarded according to
the routing table.
if-match clause
The following type of if-match clause is available: if-match acl6.
You can specify only one if-match clause in a policy node.
apply clause
IPv6 PBR supports the following types of apply clauses in
Table 12 Priorities of the apply clauses in a policy node
