Re: Just shy of OT MPLS Question

lol ... you got me. Yes, the LDP protocol exchanges labels based on ... ?

I was not technical enough in my quick answer. ;-)

I am not sure why Cisco chose this ... (other than lower overhead on core /
P routers)

I am not very knowledgeable with Juniper, but I understand that Juni can do
this with BGP? Probably someone smarter than me knows more about Juni ... I
just have not ever studied them.

What saith thee Juni guys? Super Scott has some Juni certs, maybe we can
get the super Scott to respond.

I am studying for a cvoice test! lol ... I think I am trying to fit too
much into my little brain.

Have a great night,

Andrew
