Пытаюсь настроить немножко RSVP-TE в академических целях. Как обычно начинаются непонятки при использовании разных вендоров.

Хочу настроить чтобы LSP2 использовался как основной.

лупбеки в мплс загоните.

from 172.16.16.8 уже давно не пишут - остатки прошлого.

ну и картинку то хорошо было бы

лупбеки куда загнать?:) если вы про OSPF они там есть, если как interface lo0.0 в контексте MPLS то я не уверен что поможет...

картинка есть, какую еще нужно?

чего посоветовать - проверяйте интерфейсы, фемели мплс. чего-то забыли

да это всё уже проверено..самое интересное что напрямую на 16.5 и 16.2 LSP поднимаются.

не работает именно rsvp ero

Тогда такой квест. Линк между .2 и .6 потушите и постройте лсп от.8 до .2

 

Traffic engineering в оспф прописан? Router-id везде есть?

 

Может быть, где-то есть router-id, где-то берется из лупбека, может они совпадают?

не хватало RSVP-нейбора на cat65, невнимательность :(
