[c-nsp] iBGP as MPLS labeling protocol

[Phil Bedard]

There are implementations of this using eBGP, mainly in datacenters, but you could maybe do the same thing with iBGP, NH manipulation, and RR.  There was at least one router vendor I encountered in the past that required a BGP-LU route be resolved using some underlying tunnel type like RSVP/LDP, with eBGP it automatically associated the peer interface as the NH forwarding interface.  Not sure how Cisco behaves in those scenarios.   

The configuration as someone else mentioned would likely be overly complicated and hard for most to follow once you figure it all out initially.  ☺

Subject: [c-nsp] iBGP as MPLS labeling protocol

    Hi Everybody
    
    I know this seems stupid, but I want to know is it possible to use ibgp as
    labeling protocol inside of an AS. A scenario which I have in my mind is
    establishing L2VPN connection between two PE routers while Network between
    PE routers uses iBGP(ipv4 afi/safi)?
    
    Is there anybody here who saw such implementation? I searched the Internet
    and everything I found is about Inter-AS.
    
     
    
    Thank you for your help and support
    
    Alireza
