Hi Group, I am wanting to know the difference between the following 2
expressions. I have included what I think are the correct
interpretations. Please expand upon if I am incorrect....

^100$ routes that originated in AS100 only (and that is the only AS)
_100$ routes that originated in AS100 (and there may be other ASes
prepended to this)

I have had a play on looking glass and those were my conclusions....

TIA,

JB
