Folks, can you help me here?
Please find pasted two questions on the diagram attached. Thanks again.
From a campus design point of view, fiber is associated to switches for reasons of performance. Probably the 4700 can do most what the 7200 does, but if you think you may need more features or a real router for whatever reason, keep the 7200. If you have traffic enough, you will need NPE-G1 or G2 on it.
The Cat 4500 switch might be running BGP, in order for the 7200 and the Backup router to be able to run iBGP together (if the switch is acting as a layer3 switch and not a layer 2 switch).
When talking about replacing the T1s with fiber, why eliminating the 7200 ?
HTH, please rate all helpful replies,
