Hello, All!

Может кто показать готовую конфигурацию для L2TPv3, когда концы
тунеля чистый ethernet? И схемку бы с пояснением что, откуда и куда
подразумевается.

Чтение доки на cisco не просветлило и тестовая схема 2811 + 877
не заработала. Тунель поднимается/падает и сессия не устанавливается.

2811 и 877 воткнуты друг в друга напрямую.

Конфиг 2811:
