PBR rules include a next hop list. When the rule matches a packet, the Branch Gateway routes the packet according to the specified next hop list.
Each next hop list can include up to 20 entries. An entry in a next hop list can be either an IP address or an interface. The Branch Gateway attempts to route the packet to the first available destination on the next hop list. If every destination on the list is unavailable, the Branch Gateway routes the packet according to destination-based routing.
