Sorry everyone for the inconvenience...
Got my stuff sorted out from the mess it was..
Confused the mpls with frame-relay de bit in my morning haze.
Is it correctly understood that on inbound, you cannot set L2
markings, but you can set L3 markings such as IP prec and DSCP?
Also, it is a mystery why i can set mpls exp on a frame-relay
interface thats not enabled for MPLS?
Config snippet:
R2#sh run int s0/0
Building configuration...
Current configuration : 154 bytes
!
interface Serial0/0
ip address 192.168.12.2 255.255.255.0
encapsulation frame-relay
no dce-terminal-timing-enable
service-policy input INBOUND
end
R2#
R2#sh policy-map
Policy Map INBOUND
Class class-default
set ip precedence 4
set mpls experimental 4
Again, sorry for the confusion.
