I haven't found a method of IP conservation I'm happy with while still routing at each tower. If I have MPLS underneath and use tunnels everywhere, I now have a bunch of IPs for tunnels between each PE to each tower instead of just between each router. At some number of PEs, I'll have more IPs in use there than if I just routed tower to tower.

There are two reasons, one is to conserver our ARIN allocation and to not have our internal IP space visible to customers (we are using 172. stuff) with mangle in the prerouting chain I can identify it by looking at ttl of 1. I can set the action to increment by one and get it to forward up to the next hop so the response of that and the second look duplicated. Ive tried marking the packet and setting the gateway to the loopback ip, but it doesnt seem to work, depending on what i do it either continues to go to the next hop or it just kills the traceroute. Im wondering if its got to do with the loopback being /32 or if its that im stupid, probably a little of both.
