Hi,

   

    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.

Take a look here:
