Hi all, seems like I'll finally have to bite the bullet and move BGP routing off of our Catalyst 6500. For the moment we plan a gradual migration by connecting a pair of as-small-as-sufficient routers, not switches, to the existing infrastructure to run BGP to our transit providers and leave the layer2 network in place for now.
Estimate is that the C6500 will be capable of running layer 2 plus IGP (OSPF in our case) for another year or so. We plan to move to a new data centre in that time frame, so we can build everything from scratch at the new location. For this time frame I need reliable BGP routing at the old location with a modest investment. ASR 9001 looks like a candidate, 4x 10GE and one 20x 1GE line card are definitely sufficient for the foreseeable future. Are there any licensing pitfalls I need to be aware of with refurbished hardware and IOS-XR? Can anybody share experience with the "cluster" license and feature for these switches? According to our supplier they feature 8 GB of memory and "a couple of millions of routes (v4 and v6)" - correct? Is there a viable alternative in the ASR 1k line of products? 2 rack units and low power consumption preferred. And availability in the secondary market, of course ... Any completely different product I overlooked? Thanks in advance for your input. Patrick
