Вот перевод сообщения на русский язык:
У меня такая конфигурация на LNS (MikroTik RouterBoard 500):
/interface bridge add name="Paul-Bridge" disabled=no mtu=1500 arp=disabled protocol-mode=none priority=0x8000 auto-mac=yes admin-mac=00:00:00:00:00:00 max-message-age=20s forward-delay=15s transmit-hold-count=6 ageing-time=5m
/ppp profile add name="NoIPAddr" bridge="Paul-Bridge" use-compression=yes use-vj-compression=no use-encryption=yes only-one=default change-tcp-mss=yes
/interface l2tp-client add name="l2tp-out2" disabled=no max-mtu=1460 max-mru=1460 mrru=disabled connect-to=x.x.x.x user="wifi-user" password="wifi-pass" profile=NoIPAddr add-default-route=yes allow=pap
/interface bridge port add bridge="Paul-Bridge" interface="l2tp-out2"
/interface bridge port add bridge="Paul-Bridge" interface="ether3"
По какой-то причине LNS (Cisco 7206) показывает, что туннель поднимается, а затем сразу же опускается. MikroTik отправляет запрос на отключение, и, насколько я могу судить, это не ошибка. Ниже приведен лог с LNS, демонстрирующий это.

Есть какие-нибудь предположения?
