Сначала сессия не поднималась вообще, с ошибкой в логах: Код: BGP connection is closed due to error (Code:<2> Subcode:<7> Field:<Open Opt: Strict, Err-Data present> Peer:<10.255.255.10>). После обновления прошивки до версии Build 2.84.B14 сессия стала подниматься, но через секунду связь рвется (со слов администратора второй стороны - аплинка - "роут сервер успевает выгрузить таблицу маршрутов вам после чего соединение разрывается"), в логах следующее: Код: BGP connection is closed due to error (Code:<3> Subcode:<4> Field:<Attr E-Comm: Flag(c0) !(Optional && Transitive) OR Partial> Peer:<10.255.252011-07-02, 13:03:13
BGP connection is successfully established Peer:<10.255.255.10>. Настройки такие: Код: create bgp 64636
enable bgp
config bgp router_id 10.255.255.40

config bgp neighbor general 10.255.255.10 update_source add ipif PiringLX_if
config bgp neighbor general 10.255.255.10 next_hop_self enable
config bgp neighbor map 10.255.255.10 route_map in add LX-PEER-IN
config bgp neighbor map 10.255.255.10 route_map out add LX-PEER-OUT
config bgp neighbor maximum_prefix 10.255.255.10 10000 На стороне аплинка установлен openbgpd, в его логах следующее: Код: Jul 1 22:31:06 rs.spb-lx.ru bgpd[54114]: neighbor 10.255.255.40 (WTel): state change Idle -> Active, reason: Start
