IPV6 QoS Low Latency Queuing for voice support on routers
Hi, with IPV4 you use CBWFQ with a Priority queue for voice (marked EF) traffic. However priority queuing is not supported for IPV6 traffic on routers such as the G2's (29xx, 39xx), so what are the alternative LLQ queuing mechanisms for an outbound QoS policy to give low latency? Seaching CCO I can find nothing on this subject.
Dan, yes I did see the use of classifying ipv6 traffic, but thought this would not work with a priority queue. I have just tried it and it does work. So now I have two priority queues in my policy-map, one for IPV4 and one for IPV6.
class-map match-all ipv6-voice
match protocol ipv6
match dscp ef
class-map match-any ce_ef_output
match ip dscp cs5 ef
