Additional Information
If a next hop is listed as
Discard
destination address is discarded rather than routed.
This value generally means that the route is a static
route for which the attribute has been set.
discard
If a next hop is listed as
Reject
destination address is rejected. This value generally
means that the address is unreachable. For example,
if the address is a configured interface address and the
interface is unavailable, traffic bound for that address
is rejected.
If a next hop is listed as Local , the destination is an
address on the host (either the loopback address or
Ethernet management port 0 address, for example).
There are many possible flags. For a complete
description, see the JUNOS Interfaces Command
