Multiservice Media Gateway Software Features
The Route Server module supports IP over ATM virtual routing in conjunc-
tion with the other Multiservice Media Gateway I/O modules. You can con-
figure a virtual router at the Route Server module to communicate with the
management router at the CPU module. The Route Server module can han-
dle all the in-band management traffic for the CPU module, being its default
gateway.
Virtual router concepts, network interface assignment, and the relationship
between the existing I/O modules and the Router Server module are shown
in Figure 3-19.
