Router for full BGP table

Hi Experts,

I am looking for a Cisco router for dual homing to ISPs. I will connect to two different ISPs and recieve full BGP table from them. I am comparing 3900/7200 series routers, what model would be ideal for this requirement.

I am looking for an economical solution. Please help.

Thanks

AP

Okay then, Cisco recommends a 3925 for up to 100 Mbps of WAN bandwidth, and a 3945 for up to 150 Mbps.  Cisco's recommendations are usually conservative.

If you can - go with ASR

If you can - go with ASR series of routers.

If not - 3900 is fine as long as you have minimum of 1GB RAM memory...better 3945 if it's OK.

Principle determinate, for a router, is volume of expected transit traffic.

 

For Internet BGP, you need sufficient RAM and you'll need to allow for some CPU for managing Internet route table(s).

 

As you didn't indicate the capacity of your expected ISP links, cannot recommend what "size" router might be suitable.

 

BTW, 7200s are EoL.  The 4451-X is about equivalent to a NPE-G1/G2 (depending on performance license) and the ASR1K performance starts at about NSE-1.

 ISP links would be 50Mbps

 

ISP links would be 50Mbps each. Thanks for your reply.
