We see there are two issues here (two commands in bold), the first one is IBGP issue and the second one is EBGP issue.

我用之 CCNP 300-135 新TT, MCQ, 分析找出TT的方法 (2017-06-06) ( http://bbs.hh010.com/forum.php?mod=viewthread&tid=517036&extra=page%3D2 ). 是可以分析到出來的. 但我和外國有很多網友都遇過ping的問題, 全都是ping得通. 我們想, 不知是否考試的flash 有問題. 雖然我巳溫習了300-135的書本, 但我在考試前, 巳看過這12條TT題 的所有switch 和router的show run, show ip eigrp neighbor, show ip ospf neighbor 和ping 結果. 所以我自己做了以下的筆記, 一看show run巳知每題是什麼TT. 所以以下是今天考試的TT題, 和我什樣決定出是那題TT.
