For whom it could be interesting ))
Sorry, I`ve just forgot to describe, if we were having succes with it or not
So, we implement for bbrs-vpnv4 neighbors
> set policy route-map IPCore-vpnv4-IN rule 10 action 'permit'
> set policy route-map IPCore-vpnv4-IN rule 10 set community 'none'
>
> set protocols bgp neighbor <neighbor`s ip address> address-family ipv4-vpn route-map import 'IPCore-vpnv4-IN'
after that (and reboot LNS, for a case) - bgp still lives stable with following numbers of prefixes:
