Routing between IPPs
One interconnect model is to connect a router with one interface on each IPP to route traffic between them
Normally IPP operators do not do this
- to avoid competing with ISPs for transit
- does not preclude ISPs doing this
Some possible exceptions:
- Multi-Lateral Peering Router
- Multiple-view Route Server
Other routed interconnect solutions possible but strange:
- Proxy ARP router
- Tunneling solutions
- Don’t try this at home !
