+ A BFD protocol instance accepts (by default) all BFD session requests
+ (with regard to VRF restrictions, see above). This option controls
+ whether IPv4 / IPv6 and direct / multihop session requests are accepted
+ (and which listening sockets are opened). It can be used, for example,
+ to configure separate BFD protocol instances for IPv4 and for IPv6
+ sessions.

Interface definitions allow to specify options for sessions associated
with such interfaces and also may contain interface specific options.
