I'm trying to figure out why everytime that I see a policy-map configured, it doesn't take into account the routing protocols, why is that?
I want to remark all traffic coming into our network from our BGP upstreams to be dscp 0, but I'm afraid of messing up the BGP updates. Is this dealt with automatically or do you have to compensate for BGP in the QoS policy?
One possible reason, routing protocols tend to be locally sourced and often Cisco treats locally source traffic differently from transit traffic.
For example, when you write "I want to remark all traffic coming into our network from our BGP upstreams to be dscp 0 . . .", would this be the same device that accepts the BGP packets? If so, why would there be a need to remark them?
I want to remark all external traffic entering the network to be dscp 0. I do not want this to affect the bgp communications between the two routers though. This is the same device that is accepting the bgp packets from the upstream device.

Internet security is important with the increasing attacks that are happening every day. Many internet and browsing security solutions exist, but some are not very easy to use or maybe the question is how can I enable them?
