Note To guarantee that all traffic between the proxy and other proxies is carried over the multimedia backbone, run IGRP 4000 on the 10.0.0.0 network and on the 172.22.0.0 network. Make sure that the H.323 proxy interface address (10.0.0.2) is not advertised over the data network (distribution list 10 in IGRP 5000). Doing this also eliminates the need to configure policy routes or static routes.
