Relationship between the match mode and clauses on the node
Does a packet match
all the if-match clauses
on the node?
Yes.
No.
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 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.
For more information about Track-PBR collaboration, see High Availability Configuration Guide.
Meaning
Sets an IP precedence.
Sets next hops and sets
output interfaces.
Sets the service chain
information.
Sets the default next
hop.
Permit
•
If the node is configured with
apply clauses, PBR executes the
apply clauses on the node.
If the PBR-based forwarding

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.
•
If the node is configured with no
apply clauses, the packet is
forwarded according to the routing
table.
PBR compares the packet with the next
node.
381
Priority
This clause is always executed.
Only the apply next-hop clause is executed
when both are configured.
For this clause to take effect, make sure you
have specified a reachable next hop in the
apply next-hop clause.
This clause takes effect only when no next hop
is set or the next hop is invalid, and the packet
does not match any route in the routing table.
Match mode
Deny
The packet is forwarded according
to the routing table.
PBR compares the packet with the
next node.
