Using Routers for a Converged Network
As we all know, a router is a Layer 3 device, the primary purpose of which is
path determination and packet switching based on IP or other Layer 3 addresses.
When we introduce a converged network, routers are going to have to be one of
the first places we begin to make enhancements. Cisco has developed several
routers that allow a network to make the change to a converged network. Several
new types of interfaces have emerged, utilizing the modular chassis capabilities of
Cisco’s newer routers. Now both voice and video interfaces are available for these
routers. In the sections that follow, we will discuss these interfaces and the routers
that support them.
