I have two routers each connected to an MPLS network with multiple T1's using multilink. The configuration for the multilink on the two routers is different.
Router A
interface Serial0/0/0:0
description MPLS
no ip address
encapsulation ppp
no ip route-cache cef
ip route-cache flow
load-interval 30
no cdp enable
ppp multilink group 1
hold-queue 256 out
Router B
interface Serial0/1/0
no ip address
encapsulation ppp
load-interval 30
no fair-queue
ppp multilink
ppp multilink group 1
On router a I am wondering if the "no ip route-cache cef" and "hold-queue 256 out" commands should be there and the same things for Router B "no fair-queue".

Hello Martyn,
ip route-cache cef would be good to be placed again.
hold-queue 256 out increases the output queue to 256 packets.
my guess is that someone has tried to find a workaround to some problem like losses on the multilink bundle and so he/she has disabled CEF switching and increased the size of the queue in an hope to overcome this problem.
no fair-queue: again generally speaking having fair-queue enabled is generally better.
Hope to help
