[edit protocols bgp family inet (any | flow | labeled-unicast | multicast | unicast)]
[edit protocols bgp family inet6 (any | labeled-unicast | multicast | unicast)]
[edit protocols bgp family (inet-mdt | inet-mvpn | inet6-mvpn | l2vpn) signaling]
[edit protocols bgp family inet-vpn (any | flow | multicast | unicast)]
[edit protocols bgp family inet6-vpn (any | multicast | unicast)]
[edit protocols bgp family iso-vpn unicast]

The common BGP family options are as follows:

accepted-prefix-limit {
maximum number;
teardown <percentage> <idle-timeout (forever | minutes)>;
}
loops number;
prefix-limit {
