In fact, all the route entries must have a next hop address. When forwarding a packet, a router first
searches the routing table for the route to the destination address of the packet. The system can find the
corresponding link layer address and forward the packet only after the next hop address is specified.
When specifying the output interface, note that:
• If the output interface is a Null 0 or loopback interface, there is no need to configure the next hop
address.
• If the output interface is a point-to-point interface, there is no need to configure the next hop
address. You need not change the configuration even if the peer’s address changes. For example,
a PPP interface obtains the peer’s IP address through PPP negotiation, so you need only specify the
output interface.
• If the output interface is an NBMA or P2MP interface, which support point-to-multipoint network,
the IP address to link layer address mapping must be established. Therefore, it is recommended to
configure both the next hop IP address and the output interface.
• You are not recommended to specify a broadcast interface (such as an Ethernet interface, virtual
template, or VLAN interface) as the output interface, because a broadcast interface may have
multiple next hops. If you have to do so, you need to specify the corresponding next hop for the
output interface.

You can configure different priorities for different static routes so that route management policies can be
applied more flexibly. For example, specifying the same priority for different routes to the same
destination enables load sharing, while specifying different priorities for these routes enables route
backup.
