set protocols bgp bmp mirror-buffer-limit '256000000'
set protocols bgp bmp target foo address '127.0.0.1'
set protocols bgp bmp target foo port '5000'
set protocols bgp bmp target foo min-retry '1000'
set protocols bgp bmp target foo max-retry '2000'
set protocols bgp bmp target foo mirror
set protocols bgp bmp target foo monitor ipv4-unicast post-policy
set protocols bgp bmp target foo monitor ipv4-unicast pre-policy
set protocols bgp bmp target foo monitor ipv6-unicast post-policy
set protocols bgp bmp target foo monitor ipv6-unicast pre-policy
