Connect remote networks

[chrissnop]

Hello guys, aside from VPN how to connect remote networks like a local LAN? For example, connect 3 different offices in 3 different cities. Controlled by a Central IT.

Thank you.

Hi

If I understand good you want to know how to interconnect 3 offices networks without using vpn?

If Yes, you can use:

- simple GRE tunnels (with ipsec encryption)

- dmvpn

- mpls

Is that answers your question?

Thanks

Yes definitely answer my question.

Hope you don't mind me asking again, is there some links, tutorials or videos about this?

Thanks for your input.

Hi

For DMVPN, here is a Cisco doc:

http://www.cisco.com/c/en/us/support/docs/security-vpn/ipsec-negotiation-ike-protocols/29240-dcmvpn.html

There are many others. 

For simple GRE tunnels, it's more a simple task that you have to manage. Compared to DMVPN, the advantage of dmvpn is that full mesh is done automatically. 

For mpls it's a bit more complicated and I would recommend to move forward with dmvpn or gre instead. 

Hope this is clear. 

If you need more assistance I could help you building configs but I would need more information (sketch, ips, who will be hubs and spokes, dynamic routing protocol to use between eigrp, ospf and bgp)

Thanks
