Hi, I have the following questions for ASR9001 as an Internet Gateway Router and would appreciate for your feedback.
1) Does it able to handle full BGP feed (700K+ routes) with 2 and maybe up to 4 upstream provider?
2) What is the convergence time that I can expect in the event that there's connectivity failure with any one of the upstream provider?
2) If I'm using it for IBGP, EBGP and MPLS VPN, I believe that i'll only need the license A9K-9001-AIP-LIC? Am I right?
I think that you ASR 9001 can handle full BGP even with multiple upstream providers. Only the best ones will be installed in FIB.
Here is a great doc made by Xander where you find out more:
Convergence time was around 30-40 seconds without PIC Edge because the router has to change the next-hop for every prefix and since it's more than 600K it's a long process.
Using PIC Edge we got convergence time around 5-7 seconds with Tomahawk HW.
If you are using MPLS VPN features you will need IVRF license for 8 VRF and AIP for 4K VRF. That is all you need.
