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 PBR successfully guides the
forwarding of the packet, PBR
does not match the packet
against the next node.
{
If PBR fails to guide the
forwarding of the packet and
the apply continue clause is
not configured, PBR does not
match the packet against the
next node.
{
If PBR fails to guide the
forwarding of the packet and
the apply continue clause is
configured, 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, 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 .
