The 7200 series routers with NPE-225 or higher engine are a must have for small to medium businesses that need to host internet traffic or supply large amounts of traffic within the office. The main selling points are these: 1) They are inexpensive I can grab a used 7206 with NPE-225 router with 256MB and needed interface cards for under $1000. Compare that with a 7206VXR G1. $10000 or more! Unless you are running more than 100Mbit/sec of internet traffic, you don't need a G1. 2) They support almost any interface with any protocol FastEthernet/T1/E1/T3/DS3/OC3.. well, actually if you can afford an OC3 or higher, you're probably not a small business and you'll be opting for a higher end router. Depending on the interfaces you get, you can connect using Frame Relay, ATM, HDLC, PPP, MPLS, Ethernet, HSSI. 3) They support OER If you are running a multihomed network from multiple ISP's, you don't need a full BGP routing table. If you own your own IP's, you can grab just a subset of the full BGP table and combine it with OER, which does real time pinging to destinations and will route each subnet based on which line gives better results. 4) They can be fully redundant You can run multiples of these routers using proper routing protocols, HSRP/VRRI protocols, dual power supplies, and have redundant setups. 5) Quality of service You can easily police and shape any class of traffic using CBWFQ. Or remap CoS/DSCP bits. This is just a few of the many features these routers provide. And for under $1000! Wow. There is one downside about these routers to note, but has an easy workaround. The FastEthernet modules are terrible. They do not negotiate speed/duplex properly, and you have to force your switch to full duplex 100MB in order to utilize full duplex. Otherwise you'll have CRC's out the wazoo.Read full review
This was a great router in its day, however it has reached end of life and you can not longer purchase it directly from the manufacturer. There is a recommended upgrade path to the 7206VXR; however you may want to review all your options and check your inventory. The NPE which is the processor engine is recommended to upgrade to the NPE-225 for the same reason - end of life. The 7200 series routers are modular and flexible - just remember to read the technical notes to ensure you are using the appropriate IOS code for your modules otherwise it won't work.
