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 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 a node configured
with an apply clause to the link status of a tracked next hop.
When the track entry associated with the node changes to negative because the next hop is detected as
unavailable, the node cannot be used for forwarding. When the track entry changes to positive or
NotReady because the next hop is detected as available, the node can be used for forwarding.
For more information about Track-PBR collaboration, see High Availability Configuration Guide.
