Relationship between the match mode and clauses on the node

Does a packet match all the

if-match clauses on the

node?

Match mode

In permit mode

In deny mode

Yes

If the node is configured with an
apply clause, IPv6 PBR executes

the apply clause on the node.

{

If IPv6 PBR successfully guides

the forwarding of the packet,

IPv6 PBR does not match the
packet against the next node.

{

If IPv6 PBR fails to guide the
forwarding of the packet and

the apply continue clause is

not configured, IPv6 PBR does
not match the packet against

the next node.

{

If IPv6 PBR fails to guide the

forwarding of the packet and

the apply continue clause is
configured, IPv6 PBR matches

the packet against the next

node.

If the node is configured with no

apply clause, the packet is

forwarded according to the

routing table.

The packet is forwarded according
to the routing table.

No

IPv6 PBR matches the packet against
the next node.

IPv6 PBR matches the packet against
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 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.
