I have followed all of the configuration steps given for egress accounting with netflow on a MPLS VPN link. However, it is only showing flows coming into the router. I need to be able to account both ways- any recommendations? Config below:
interface Multilink12
mtu 1580
ip address XX.XX.XX.XX 255.255.255.252
no ip redirects
no ip unreachables
ip pim sparse-mode
ip route-cache flow
mpls netflow egress
mpls label protocol ldp
mpls ip
ppp multilink
ppp multilink group 12
ip flow-export source FastEthernet0/0/0.10
ip flow-export version 5
ip flow-export destination XX.XX.XX.XX 9996

Update on this- Im now receiving all traffic incoming into the interface, but am tracking only about 10% of the outgoing traffic- revised config below:
ip flow-cache timeout active 1
ip flow-cache mpls label-positions 1 2 3
ipv6 flow-cache mpls label-positions 1 2 3
interface Multilink12
mtu 1580
ip address XX.XX.XX.XX 255.255.255.252
no ip redirects
no ip unreachables
ip flow ingress
ip flow egress
ip pim sparse-mode
ip route-cache flow
mpls netflow egress
mpls label protocol ldp
mpls ip
ppp multilink
ppp multilink group 12
service-policy output cbwfq-voice20per
ip flow-export source FastEthernet0/0/0.10
ip flow-export version 9 origin-as
ip flow-export destination XX.XX.XX.XX 9996
