On a multilink configuration with 2 or more member links, using priority queuing (CBWFQ) for voip, should the serial members have no fair-queue configured?  what is the implication of no doing this?

interface Multilink1
 description => MPLS VPN
 ip address x.x.x.x x.x.x.x
 load-interval 30
 no cdp enable
 ppp multilink
 ppp multilink fragment delay 10

 max-reserved-bandwidth 100
 service-policy output llq-policy
!
interface Serial0/0/0
 no ip address
 encapsulation ppp
 ppp multilink
 ppp multilink group 1

Based on the config above, a service policy is configured. It is within this service policy that fair queueing would be enabled if you were to use it. Fair queueing will help balance traffic flows, but is only really affective on lower speed links.

There is no need to disable fair queueing on the interfaces themselves, I believe it is disabled by default on any interfaces with a bandwith of more than 2 Mb, but this won't interfere with CBWFQ anyway.

I wouldn't recommend using the maximum-reserved-bandwith command however, this will allow you to allocate 100% of the bandwith in CBWFQ, something Cisco do not recommend.
