We have 2 offices and a collocation facility office A, office B, and the colo. Office A has about 300 users and office B has about 400 users. The colo houses our intranet sites and we route our internet traffic from the offices through the colo. The colo currently has a Cisco 2620 with a network module for 4 T1s.
Office A (Cisco 1720) has 2 dedicated point to point T1s (multi-linked) to the colo for access to the intranet, internet access, and connecting the office A and office B.
Office B (Cisco 1841) has 2 point to point T1s (multi-linked) to the colo for access to the intranet, internet access, and connecting the office A and office B.
At office B we are removing the 2 data T1s to the colo and replacing it with one (1) 50 Mbs ethernet connection. So we need to replace the router in colo with a router that has 2 T1 ports (for office A) and 2 ethernet ports (1 for offce B and 1 for routing in the colo). I like the 1841 because it already has the 2 ethernet ports and I think with one (1) VWIC (CIS-VWIC-2MFT-T1) we can do what we want.
I need to be sure that the 1841 router will not have any processing limitations for what we want to do. Basically is the 1841 router big enough to handle this type application? or should I look at the 2821?
Any suggestions would be appreciated.
