Hello I have several sites with one static ip, i am using crypto maps to link them toghether, i would like to set up a gre tunnel to pass eigrp . Do i need to use a second static ip for this? can this be done with the same ip of my external interface? or can it just be dummy ip?
is there any other way to setup a mesh without seting up gre tunnels? another protocol?
I am preatty new to cisco and i am struggling to get the routing working. thanks.
