I want to replace our 7206 edge router with a 4900M. The switch has 512MB and lots of options for GE & 10Gig. Obviously, the usual progession would be to a 7600, but the layer 3 switch has more than enough memory to store 2 full BGP routing tables (eBGP & iBGP). Also, the 4900M has the throughput that costs a fortune on a high end edge router. Could anyone tell me why this is not a good option?
I agree that the 4900M would be a much feasible option in terms of throughput unless you require advance features to be supported by the box
However the existence of 512Mb memory alone would not help to store 2 full BGP tables. As per the data sheet, the max entries that the 4900M supports is 200K (including unicast and multicast). If you really want to store that many routes, you should be looking at a diff platform
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
