Re: 7206 VXR NPE-G1 throughput

The ACL is a recent addition and we can probably do away with it. I didn't notice a significant increase in CPU or drops since adding it. But we usually peak at about 200Mbps on this link. The full routing table is a must since we're dual homed.

We're still on the 12.4 train. I do use an ACL with less than 100 entries which handle BCP38 and block a few bad actors 
and private IPs on the Internet. I will be moving the BCP38 ACL closer to the
hosts before the upgrade so the ACL will be a bit shorter in the future. We won't be doing any QOS or IPv6 on it but it 
does take a full BGP table. I just need it to last another year or two out of it
if possible. I believe this platform goes End of Support in  Spring 2016.

We are looking to double the bandwidth on one of our circuits from 300Mbps to 600Mbps. We currently use a Cisco 7206VXR with 
an NPE-G1 card. These seem like very popular routers so I'm hoping a few
people on this list have them deployed. If you or a customer have these deployed, how much bandwidth have you seen them 
handle? This will be handling dorm traffic at a college so it's mostly download.
The 7206 handles our 300 Mbps circuit just fine, but we are moving it to our 600Mbps circuit. At peak we've seen the 
following numbers for that circuit:

    30 second input rate 559982000 bits/sec, 55809 packets/sec
    30 second output rate 55429000 bits/sec, 32598 packets/sec
       267756984712 packets input, 333325152556755 bytes, 0 no buffer

This is the interface that connects to our provider. As you can see its almost all download traffic. Our ASR1002 handles it 
without a sweat but I'm a little skeptical of whether the 7206 will hold up.
This depends on multiple variables. The 7200 is a single-CPU platform where CPU can go sky-high when using features like 
ACL's, QoS, IPv6 and you name it.. Also, changing from IOS 12.4 to 15 increased
our CPU usage with another 10%+. Stick to the bare minimum of features you really need and you will be fine.

Full routing and ACL 100+ entries? I would ditch the 7200+NPE-G1 or upgrade to an NPE-G2..
