R2511-HP MSR Router Series Layer 3 - IP Routing Configuration Guide(V5)

All packets can match a node where no if-match clauses are configured.
If a permit-mode node has no apply clause, packets matching all the if-match clauses of the node are
forwarded according to the routing table.
If a node has no if-match or apply clauses configured, all packets can match the node and are
forwarded according to the routing table.
PBR and Track
You can use Track to monitor the output interface, default output interface, next hop, and default next hop
for PBR so that PBR can discover link failures faster. PBR takes effect when the status of the associated
track entry is positive or invalid.
For more information about Track-PBR collaboration, see High Availability Configuration Guide.
