must not have an interface name specified.

Description 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.
Default no protocol — No route source for the route unknown priority event is defined.
Parameters bgp — This parameter defines BGP as an eligible route source for a returned route prefix from
the RTM when looking up the route-unknown route prefix. The bgp parameter is not
exclusive from the other available protocol parameters. If protocol is executed without the
bgp parameter, a returned route prefix with a source of BGP will not be considered a match
and will cause the event to enter the set state. This parameter only applies to the 7750 SR and
7950 XRS.
bgp-vpn — This parameter defines bgp-vpn as an eligible route source for a returned route prefix
from the RTM when looking up the route-unknown route prefix. The bgp-vpn parameter is
not exclusive from the other available protocol parameters. If protocol is executed without
the bgp-vpn
parameter, a returned route prefix with a source of bgp-vpn will not be
considered a match and will cause the event to enter the set state. This parameter only applies
to the 7750 SR and 7950 XRS.
