dscp marking on DMVPN

mickd08
Level 1
Level 1

Hello, I have an Internal private network over which a DMVPN is running. I am wanting to mark all packets egress from the hub and spoke routers to be marked dscp 46 such that the IPSEC-GRE packets will traverse the private network with expedience. Is it the best way to do this by simply applying the service-policy to the physical WAN interface of the the hub and spoke routers ?

i.e.

policy-map all-traffic

class class-default

set ip dscp EF

 

int WAN 

service-policy output all-traffic

Hello,

 

basically for this to work, you apply the service policy to the physical interface, and then configure 'qos pre-classify' on the tunnel interfaces.

 

interface Serial0/0/0

service-policy output QoS_Policy

!

interface Tunnel0

qos pre-classify
