It’s quite exciting topic 🙂
Multihoming is when a host or network is connected to one or more (multiple) Internet Service Provider (ISP) or we can say it has multiple up links.
As by know there are few RFC for multihoming approach such as from RFC7157. Try to read it for list of scenarios and also techniques. For know I just want to achieve load balancing over the multiple up-links, or at least have fail over.
At first I decided to have topology like the diagram below, two ISP connected to a single home router, the host then can connect to this router and will be assigned at least two IPv6 addresses from only one network interface.
Less than 3 hours after I purchased the 3G/4G Wireless N Router TP-Link, model TL-MR3020 the router already been flashed with custom firmware you know OpenWrt 🙂
This guide is just my notes, as somehow I need to re-flash again but I glad if it helps you.
The original version before flash.
Firmware Version: 3.14.2 Build 120817 Rel.55520n
Hardware Version: MR3020 v1 0000000
Who know someday I would need to share my 3G internet to a wifi router. I have TP Link WR740N and Celcom 3G Huawei modem connected to my Windows 7 PC and it’s quite tricky to set this 3G as a WAN. When I google , I found most of the peoples don’t really get the solution when they are asking through forum, so I am going to share my step the wifi.
This is my sketch of the network I want to build.
Referring to the picture above might explain the bridging concept I want to create to my network. I’m actually setting up Xen VM, and one of the server I disconnect from public access through internet. Well, if you ask why the VM can be installed with program like databases which don’t require public access on it.
