When more than one next hop IP addresses are eligible for matching, a next-hop command must be
executed for each IP address. Defining the same IP address multiple times has no effect after the first
instance.
The no form of the command removes the ip-address from the list of acceptable next hops when
looking up the route-unknown prefix. If this ip-address is the last next hop defined on the route-
unknown event, the returned next hop information is ignored when testing the match criteria. If the
ip-address does not exist, the no next-hop command returns a warning error, but continues to
execute if part of an exec script.
no next-hop — No next hop IP address for the route unknown priority control event is defined.
ip-address — The IP address for an acceptable next hop IP address for a returned route prefix from
the RTM when looking up the route-unknown route prefix.

This command adds one or more route sources to match the route unknown IP route prefix for a route
unknown priority control event.
If the route source does not match one of the defined protocols, the match is considered unsuccessful
and the route-unknown event transitions to the set state.
The protocol command is optional. If the protocol command is not executed, the comparison
between the RTM prefix return and the route-unknown IP route prefix will not include the source of
the prefix. The protocol command cannot be executed without at least one associated route source
parameter. All parameters are reset each time the protocol command is executed and only the
explicitly defined protocols are allowed to match.
The no form of the command removes protocol route source as a match criteria for returned RTM
route prefixes.
To remove specific existing route source match criteria, execute the protocol command and include
only the specific route source criteria. Any unspecified route source criteria is removed.
no protocol — No route source for the route unknown priority event is defined.
ospf — This parameter defines OSPF as an eligible route source for a returned route prefix from the
RTM when looking up the route-unknown route prefix. The ospf parameter is not exclusive
from the other available protocol parameters. If protocol is executed without the ospf
parameter, a returned route prefix with a source of OSPF will not be considered a match and will
cause the event to enter the set state.
is-is — This parameter defines IS-IS as an eligible route source for a returned route prefix from the
RTM when looking up the route-unknown route prefix. The is-is parameter is not exclusive
from the other available protocol parameters. If protocol is executed without the is-is parameter,
