Route policies contain policy statements containing ordered entries containing match conditions and actions you specify. The entries should be sequenced from the most explicit to least explicit. IGMP group membership report processing can be implemented according to your defined policies. Policy-based routing allows you to dictate whether to process or drop the traffic. Route policies can match a specific route policy entry and continue searching for other matches within the same route policy.
The process can stop when the first complete match is found and executes the action defined in the entry, either to accept or reject packets that match the criteria or proceed to the next entry. You can specify matching criteria based on source or destination.
You can also provide more matching conditions by specifying criteria such as:
prefix list
A named list of prefixes.
From criteria
A source IP address and destination (for example, a destination IP multicast group address).
