При принятии префиксов короче чем /13 проблем нет.
Далее при "подливании" префиксов по /20 начинаются проблемы. Лечится командой clear cef linecard до перезагрузки коробки либо начала заливки еще более длинных префиксов..
При изначальной заливке full-view с длинной до /24 проблема воспроизводится тоже.

У нас как и у автора темы во все стороны etherchannel настроены по 2-4G, есть подозрение что есть связь какая-то, у него тоже через RP трафик бегает похоже. Поэтому и спросил чем у него история закончилась.
