We have implemented our QoS Policies throughout our network. DSCP tagged EF and CS6 packets are being prioritized correctly on all of our interfaces with the exception of the BGP connected link. CS6 packets are being prioritized, however, EF packets (RTP traffic) is not. The BGP link is using VRF VPN's- does this have something to do with it? Is there something special that has to be done to be able to prioritize this traffic?
Do you mean EF is not being tagged when you capture the RTP on the other side of the BGP link? I suppose you need to check with your BGP provider. Sometimes they'll strip it, or if their router doesn't know the TOS it'll strip it. It's usually another way to get you to buy QOS from them.
Actually, we are tagging traffic ourselves as it comes into our router. EF IS being tagged correctly, and going outbound toward the serial, ethernet, and multilink interfaces it is prioritized correctly going out. On our BGP connections between core routers and to provider edge routers, it is not. All of these BGP links are within our system- no external provider.
