We have actually a cisco 3660 with multiple Fast Ethernet interface connected to different catalyst switches and on our WAN a link at 45 Mbps almost fully used. We are planning an increase of the WAN to 155 Mbps next year and planning to upgrade our equipments. We were thinking about a 7206VXR with an NPE-G1 or G2 card + Fast Ethernet interfaces etc... Someone told us we'd better use a catalyst 4506 with a supervisor engine V and relevant Fast Ethernet interfaces (so we can get rid of the switches).
We are just doing static routing, ACL and Vlan 802.1q.
I need any comment or recommandations about what can be the best to do.
Thanks for any comment.
