Pbr And Track; Pbr Configuration Task List - HP VSR1000 Configuration Manual

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 object. The tracked object can be a next hop, output interface, default next hop,
or default output interface:
• 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.

If the node is configured with apply
clauses, PBR executes the apply
clauses on the node.
•
If the node is configured with no
apply clauses, the packet is
forwarded according to the routing
table.
PBR matches the packet against the next
node.
Configuring a policy:
If the PBR-based forwarding
succeeds, PBR does not match the
packet against the next node.
If the PBR-based forwarding fails
and the apply continue clause is
not configured, PBR does not
match the packet against the next
node.
If the PBR-based forwarding fails
and the apply continue clause is
configured, PBR matches the
packet against the next node.
