Page 280 highlights

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 being unavailable, the node cannot be used for forwarding. When the track entry changes to positive or NotReady because the next hop is detected as being available, the node can be used for forwarding.

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
being unavailable, the node cannot be used for forwarding. When the track entry changes to
positive
or
NotReady
because the next hop is detected as being available, the node can be used for forwarding.
