Extend LAN on internet

Dear All,

 

How I can extend my LAN from head office to remote branch. So that I can use some IPs a /24 class at head office and some IPs of same class at remote branch.

Lan 1 (192.168.1.0/24)----Ho RTR------Internet------Branch RTR----Lan 1 (192.168.1.0/24)

My service provide is not MPLS enabled.

 

Thanks,

Anjum

  • You can run L2TPv3 or bridge IP over a GRE tunnel. Both are independent of the provider as long as you have IP reachability between sites.

  • Dear Brian,

     


    Thanks for
    your reply.

    I am studying
    both technologies. Can we establish one more remote branch and use the same IP subnet
    in new remote branch. Is it workable with multiple tunnels.

     

  • L2TPv3 is point-to-point only as far as I know. You may be able to hack bridging over multipoint GRE, but I've never tried. This design is mainly what the VPLS and OTV features are designed to accomplish.  VPLS is an MPLS feature, and OTV is most likely overkill for your design. 

    What exactly are you trying to accomplish? There is most likely a better way to solve the design besides extending the layer 2 domain. Post more of your design details and I'd be more than happy to help.

  • Dear Brian,

     

    Thank you very much for your great interest in this porblem and solution. I draw 2 diagrams to show existing scenario and new proposal with Bridge IP over Multipoint GRE. But I dont know how to share these diagrams here in this fourm as far as these diagrams are in my files in my profile in this forum.

     

  • Dear Brian,

     

    Diagrams are sent to you through email.

     

    Thanks,

    Nadeem Anjum
