[AusNOG] Juniper CX111 Failover for Cisco 870's

[Ben Dale]

I haven't had got my hands on one of these yet, but I believe they will - the CX111 is an OEM from Cradlepoint (you can see the WiPipe logo on it here: 

http://www.juniper.net/techpubs/hardware/junos-cx/cx111/cx111-quick-start/cx111-quick-start.pdf 

and it looks more than a little similar to this:

The JUNOS app note for configuration gives a few clues:

you essentially set up your router's ethernet port up as a DHCP client (receiving an address and gateway from the carrier via the CX111), then you can use whatever fail-over detection method you want.

Cheers,

Ben

Cisco are our router of choice for our customers so we have hundreds of them already deployed. Or if anyone knows of a device that can bridge a 3g connection so the IP from the 3g connection will still terminate on the Cisco I would be very grateful for your recommendations.
