Relationship between the match mode and clauses on the node
Does a packet match

if-match clauses
on the node?
Match mode
Permit Deny

If the node is configured with
apply clauses, PBR executes the
apply clauses on the node.


succeeds, PBR does not
compare the packet with the
next node.

If the PBR-based forwarding
fails, PBR does not compare
the packet with the next node.
•

No.
PBR compares the packet with the next
node. PBR compares the packet with the

PBR and Track
PBR can work with the Track feature to dynamically adapt the availability status of an apply clause to
the link status of a tracked next hop or default next hop.
•
When the track entry associated with an object changes to Negative , the apply clause is
invalid.
•
When the track entry changes to Positive or NotReady , the apply clause is valid.
