Router for 100Mb WAN link.

Hello,

I'm looking into upgrading my WAN link to 100Mb via Fast Ethernet link. I'm waiting to hear from ISP about what exact technology they use, but according to my manager they will be coming in over fiber and then terminate to copper. I currently have 2811 in production with two T1 cards bundled together. 2811 has basic configuration with only 2 ACLs. I have ASA 5510 for NAT, Ipsec and other services. What router or networking device (layer 3 switch, such as 3560G perhaps??) should I use to accomodate 100Mb link? It seems that 2811 will not handle that kind of bandwith..In short the max recommended bandwidth limits for the 28xx series are as follows:

2801--2 Mbps

2811-4 Mbps

2821-8 Mbps

2851-12 Mbps

I don't want to create a bottleneck and am looking for appropiate solution to accomodate 100Mb link. Also, could ASA 5510 become a bottleneck in my scenario?

According to Cisco docs ASA5510 can handle 300Mbps of firewall througput, but I'm not sure how it'd work in production...

Thank you,

forman

Full Duplex, UN-encrypted traffic = 2921 or 2951

Full Duplex, Encrypted traffic = 3925
