Failover

In order to configure a failover system you need the following

Two internet service provider
three sets of ip address
OSPF routing protocol.
two interface card for each server

You need a common ip address for your DNS server the one you have registered .

to setup :

[code:1]
Provider A ........................................................Provider B

---

......................................

---

|wanIP_A | ........................................ | wanIP_B |
|router A | ........................................ | router B |
|LanIP A | ........................................ | LanIPB |

---

............................................

---

\ ............................................................. /
\ ............................................................. /

---

| lanIP_A LANIP_B |
| loopbackip lo (127.0.0.1) |
| loopbackip lo:1 (Common IP_C) |

---

DNS Server[/code:1]

You need to enable OSPF routing (i use gated)

Pitty the formation of your graph was destroyed by the script. Could you try posting it again in [code] tag because it seems interesting?

Thanks!

hi

yes kindly repost the graph and i think this is a great topic..i would like to learn also how to implement a faliover on the network in cases that problems occur over the network...

I've tried to add the [code] tags in order to preserve the diagram but I'm not sure if I've done it correctly, so we'll need jhundpogi to confirm this for us.

I must say its a very interesting topic and something you won't see covered in detail on many sites!

ah now it makes sense


Thank you for taking the trouble to reconstruct it Chris!
