how to config qos to classify ospf/bgp protocol traffic in MPLS vpn network

[flyjunli]

hi,

i config two qos class, one is for voice ,using EF ,exp 5, other using exp 3 for critical traffic.

my question is how to classify traffic such as ospf,ldp,bgp core protocol into appropriate qos level,do i need config these traffic into ip tos/exp 7 or 6. or there is a default behavior in router for these traffic , i don't need to do anything.

thank you!

Tom
