have a question here about MP-BGP (iBGP) updates sent to PE or RR.
You know, when BGP prepares the update, put the source and destination IP which a Loopback address, then it has to lookup for the next hop to send the update. The next hop IP will usually already have LDP label associated with it. Does this label add into the BGP paket update so in other word the update itself is labelled switch inside MPLS core. Thanks
