MPLS VPN without MP-BGP !!?

hi,

 

I am just curious,

 

is there another way to configure MPLS VPN without MP-BGP?

  • VRF lite but you would have to configure the VRF on every router in the path to keep the private customer IPs private - pretty manual and an administrative headache

  • Actually scrap that - that wouldnt work - you would have to have a subinterface on each router through the CORE for each customer, in order to assign a different VRF to each customer - then label it, in which case whats the point of MPLS / labelling.  Bad idea and didnt think it through well enough - sorry

  • You have to remember the point of MP-BGP with MPLS VPN. You are exchanging VPNv4 information with PE devices so that any PEs that are exchanging Route-Target (import and export) that you'll be able to receive the updates. I respect the desire to know if another way is possible, I encourage that. I also encourage the desire to know exactly why you would have MP-BGP in the first place. If you do, bravo. Keep up the good work, I enjoy these type of questions.

  • Why do you need BGP for VPN's to begin with , not design wise but what does it do? It advertises customers routes and labels for those; as no other protocol can don that, it means the only other solution would be to do static routing for customer routes and static labels for customer routes.
