I'm trying to configure two routers cisco 4431, first one will be active second one will be backup router, and i'm trying connect this routers with VRRP throught Sub interface. These two routers will be central hub for DMVPN tunnels. My question is will VRRP work with DMVPN? how can i do this? Will DMVPN tunnel works normal with these two routers connected by VRRP or i will have some problem with it? Please give me some advice
