У мене виникає проблема з підключенням VPLS за допомогою ME3600x з сигналізацією 15.3 (2) та BGP. @yelfathi та @packettalk вказали мені на правильний маршрут, але не знають, як його вирішити.
У мене є 2 перемикача ME3600, які використовують RSVP як PE та 2 маршрутизатори MX80 як P.
На маршрутизаторах P показано, що LSP правильно проходить LSP, і мої TE тунелі підняті. На обох перемикачах я отримую наступне:

після деякої допомоги від @ytti ми звузили його до помилки в Me3600 щодо сигналу BGP.
Ми змінили сигналізацію на LDP, і вона спрацювала нормально. Опублікував оновлення, коли буде вирішено Cisco.
