[HELP] Route Maps question

I have been told at work to look at this and see if we need all this junk. It was implemented long time ago by people that left the company

the MARK-INBOUND-LAN is applied to all sub interfaces that are facing LAN

interface GigabitEthernet0/1.1
 description Data LAN
 encapsulation dot1Q 1
 no ip redirects
 no ip proxy-arp
 ip flow ingress
 ip pim sparse-mode
 ip nat inside
 ip virtual-reassembly in
 ip verify unicast reverse-path

I have never played with this before, but maybe someone here has and I would appreciate any suggestions on this topic.

Well its a QoS config thats for sure, but done in an interesting way, using route-maps. Have never seen it done like that before.

Whether you need it is probably not something we can say. This is up to you and your business requirements.

It looks to me like its giving lower priority/smaller bandwidth to less desirable network services, like file sharing, while giving real time applications like voice/video etc higher priority.

To me that sounds like a reasonable thing to do.

Maybe all you need to do is to revise the list of applications that should have higher/lower priority. Maybe you need to re-write it. I dont know. What do you want to do?

Where in any of that was there a "route-map"?

Hm you are right. I must have read that too quickly after a hard days work. Probably mistook policy-map for route-map.

Apart from that I guess what ever else I said still stands. :-P

This is an MQC set up for an admission of traffic inbound on a trunk interface. The class-map defines specifics and Policy police the inbound traffic.

It has been very well defined Class-Maps. I am not quite sure why you'd want to get rid of them

I want to go over some of those class-maps in more detail... I get a sneaking suspicion some of them may be
redundant in the grand scheme of things. Otherwise as Da Geek Kid mentioned, if it works well, there's little
reason to remove. It never hurts to review your bandwidth and loads on each class and see if a (re)adjustment
is needed.

My 00000010bits.
