Yep, an invalid as-path attribute was injected from somewhere. Our as-path sanity check code failed to catch this case.
thank you for this nice code, which caused our gated to crash... Where may i send my bill to :-)))
We have opened the following ddts:
====== Bug ID : CSCdk63586 Project: CSC.sys Status : O 3 encls Product : all Found : customer-use Care Update: N Versions : 11.1CC Headline : BGP: Tighten as-path sanity check
fine to see, that it is corrected in 12.0(2)S. This will be another reason for cisco to force everybody to throw away 11.1.X up to 11.3.X....
