While we are a bit diverging from original topic and while indeed under very careful application there could be some use cases for outbound bgp policies even for ibgp I have never seen one to be applied inbound - which was the point of my comment. So for educational purposes could you describe

Gents, I have a green field IPv6 infrastructure that I am standing up, I plan on allocating unique IPv6 net block ranges for infrastructure nets (loopbacks/routerid, pt-to-pts), service delivery allocations (customer services), North of the security boundary layer, south of security boundary

Hi! I have a Cisco ASR1004 running IOS 12.2(33)XNF2 on IOS XE 02.06.02, which for some reason, does not return cbQosIfIndex for some interfaces. For example, here is an interface with input service-policy configuration applied: asr1004#sh policy-map interface TenGigabitEthernet1/1/0.260 input

Nicolas covered the RIB speed in the blog as well, and had varying results, but on average about 10s for today's full table. The bottleneck in the operation is usually the advertising router, not the local router populating the RIB. I don't think there was a test where the FIB took more than
