Folks, what's the minimum image I should use if I need to run BGPv4 on my 2851 router?
I know that the c2800nm-advipservicesk9-mz.124-9.T5.bin will do BGP for example, but my question is, is this the image the one can give me BGP and it is the most cost effective one?
I know how to use the feature navigation software, but I see so many images there which can support BGP that it is hard to find out which ones are the minimal I need.
I believe that BGP in the Advanced Security image has been a moving target. A while back I remember looking and there was no support for BGP in the Advanced Security image (I had a customer running the Advanced Security image who wanted BGP). I just tried it on a router running 12.4(15)T and it lets me configure BGP just fine. I am not clear whether it is an early 12.4/later 12.4 thing or a 12.4/12.4T thing. But I can tell you for sure that there are some versions of the Advanced Security feature set that do have BGP support.
