Hi,
I need to config the new router but I need some details of your router.
The topology is the next.
ISP 1 > Cisco 800 -> Cisco 881-4G (with SIM, ISP2) -> LAN
I know that this topology is a little rare but I must config with these devices.
Cisco 800 have the network 192.168.1.1 255.255.0.0 and I can´t change it. I must config the Cisco 881-4G with FailOver.
I have the next code however I don’t know if I will have any problem with this.
Maybe I have to do the Cisco 881-4G a mix of Switch/router ( I don´t know if I can do it) because I don´t want to change the gateway of every device of the LAN (192.168.1.1)
Could anybody help me please??
Thanks in advance.
Regards.
