Hey group,
I have the following topology:
LAN Users connected to ->Layer3 switch F0/48->connected to->F0/0 of Router - serial link connected to->WAN
( F0/1 connected to-> ADSL IPsec VPN link
The Router is connected to layer 3 switch via F0/0
The router also has one serial link to a private WAN and an ADSL link via F0/1
Requirement on the 12.3 IOS Layer3 switch:
Classify only HTTP traffic from all LAN users with DSCP AF21
Requirement on the 12.3 IOS Router:
Using PBR send only traffic marked with DSCP value AF21, received from the LAN, out via ADSL link.
All other traffic send out via serial WAN link.
Can I use Modular QOS to classify HTTP traffic, set ip dscp AF21, and then apply the service-policy output policy1 to the egress F0/48 connecting on the switch?
Switch example:
Switch(config)#access-list 101 permit ip any any eq www
Switch(config)# class-map match-any class1
Switch(config-cmap)# match access-group 101
Switch(config)# policy-map policy1
Switch(config-pmap)# class class1
Switch(config-pmap-c)# set ip dscp af21
Switch (config)# interface f0/48
Switch (config-if)# service-policy output policy1
On the router I would create route-map to match all IP DSCP af21 and set interface f0/1. Then apply the ip policy route-map to the f0/0 interface of the router.
If this setup is not possible, what is another possible solution for classifying traffic on the layer 3 switch so when the router receives this traffic, it can Policy-Base Route it via ADSl link.
Thanks
Will
