I just wondering what are the ways that we could implement L3VPN
L3VPN using MPLS/BGP
And what could be possibly other model that we could implement L3VPN
Solved! Go to Solution.
What do you mean by "ways to implement L3VPN"? By other ways to implement L3VPN, you mean like other Layer 3 VPN types? a GRE tunnel is also a Layer 3 VPN for example.
Yes, Exactly Various L3VPN type
1) MPLS/BGP L3VPN
2) GRE/BGP L3VPN
So it that ok to say these are only those types.
Sorry I am just preparing myself to understand these technologies, so I would like to Know all available L3VPN types so that I could try to gain knowledges on those types.
EVN based on VRF-lite without BGP or MPLS but mostly for small/medium businesses.
