Does a packet match
all the if-match clauses
Permit Deny
No.
PBR compares the packet with the next
node.
PBR compares the packet with the
next node.
A node that has no if-match clauses matches any packet.
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 object. The tracked object can be a 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.
For more information about Track-PBR collaboration, see High Availability Configuration Guide.
