How to set up a tunnel in cisco 881 and 880?

Question

Cisco

Hello people.
I have 2 cisco 881 and 880. It is necessary to set up connectivity between two objects via the Internet.
I created a tunnel interface and 2 vlan interfaces on the gateways, I also registered a static route (pings ran). But the Voip gateway is statically configured, but I would like to receive ip via dhcp.
Yes, and for the first time I set up cisco, there is a feeling in the clumsiness of the settings.

Answer 1

As a result, they knocked out 2 white ip. And configured l2tpv3 + gre ipsec.
Gateway gets ip via dhcp.
