[j-nsp] can i see bgp looped AS PATH prefixes on the receiving router

[Aaron Gould]

I wonder if confederations are creating the difference with what y’all are expecting to see ?  In other words, perhaps confederations don’t show loop AS’s as hidden.  Just guessing as I learn…

 

Here’s both sides, of what is sent from r5 and what is received on r4 ?
