Привет! Я сегодня бьюсь головой об стену, никак не могу заставить работать IBGP v6. Проблема возникает на нескольких роутерах, но для примера я сосредоточусь на двух, думаю, исправление поможет и остальным.
Роутер 1 - AS1001
Роутер 2 - RB1100x2 - v5.18
Оба роутера подключены к одному коммутатору.
**Конфигурация Роутер 1:** (ipv4 часть убрана)

На Cisco я вижу, что маршруты рекламируются – в частности, 2402:7E00::/32 rt-nztg-sky-core01#show bgp ipv6 unicast neighbors 2402:7E00::3 advertised-routes | in 2402:7E00::/32 *> 2402:7E00::/32 :: 0 32768
На Mikrotik я вижу, что маршрут выучен, но статус - недостиг. Соответственно, он не устанавливается в таблицу маршрутизации и не рекламируется внешним пирам.
```

```
Из Mikrotik, если пинговать 2402:7e00::7 через Winbox, то приходит ответ с 2402:7e00::1:11.
Похоже, я что-то упустил... Буду очень благодарен за любую помощь.
