QOS

10mb 512kb

LAN--->router1---->router2--->WAN cloud--->HQS router

I am planning to implement QOS policy on router1 outbound interface for VOIP traffic.I do not have controll over router2 for QOS configuration. do u know if, once VOIP traffic leave my router1 outbound interface will have end to end QOS or guranteed bandwidth for voip traffic ?

Here is my sample config on router1

Router(config)# class-map voice

Router(config-cmap)# match ip dscp ef

Router(config)# policy qos-policy

Router(config-pmap)# class voice

Router(config-pmap-c)# priority 24

Re: QOS

For QOS you will have to configure in all the devices in the path source to destination.

QOS configured on router 1 will guaranty only till the packets leave RTR1. After that it does not have any control.

Re: QOS

Thanks for your expert advice. So, there is no way that you can mark packet with high priority and have guranteed flow all the way through destination???...

Re: QOS

The packet will retain the marking of high priority but if the equipment on the other side is not configured to even pay attnetion to that designation then it is just as preddyi said. Once it leave your router it becomes a "best effort" deal.
