Does anyone have an example of a running config where you have a gre
tunnel and running VOICE QOS.
I think I have it figured out but I am not for sure.
Here is a sample of the config



class-map match-all VoIP-Control
  match access-group name VoIP-Control
 class-map match-all VoIP-RTP
  match access-group name VoIP-RTP
!
!
 policy-map child
  class VoIP-RTP
   priority percent 70
  class VoIP-Control
   bandwidth percent 5
  class class-default
   fair-queue
   set dscp default
 policy-map tunnel
  class class-default
   shape average 1500000
   service-policy child

interface Tunnel1
 bandwidth 1500
 ip address 192.168.133.2 255.255.255.0
 service-policy output tunnel
 tunnel source Ethernet0/0
 tunnel destination 192.168.100.253

ip access-list extended VoIP-Control
 deny   ip any any fragments
 permit tcp any any range 2000 2002 dscp af31
 permit tcp any any eq 1720 dscp af31
 permit tcp any any range 11000 11999 dscp af31
 permit udp any any eq 2427 dscp af31
 permit tcp any any eq 2428 dscp af31
 permit tcp any any eq 2748
ip access-list extended VoIP-RTP
 deny   ip any any fragments
 permit udp any any range 16384 32768 dscp ef

Thanks in advance.
