Re: Interrogation mark at the end of the as-path
Hi Adrian,
The interrogation sign is always present. Please ignore them for the purpose of questions related to the lab.
I'm not sure why FRR/Quagga projects have chosen to put it but, as far as my observation is concerned, I suppose they mean the AS-Path can be longer if the actual originator of the network is not the last AS but some other AS. The question mark probably depicts this uncertainty.
If someone knows a better explanation, I'm happy to hear that. I'll also check that on the FRP project and update here in case I find a better explanation.
Thanks,
Jagdish
