Description (partial)

Ping with MPLS OAM comes back with a DS-MAP mismatch flag on load balancing paths.

Differences in the CEF hashing mechanism between the RP and the line cards in a load balancing scenario. This can be checked by using the following commands. 

show cef exact-route <Source IP> <Destination IP> loc <Location of RP>
show cef exact-route <Source IP> <Destination IP> loc <Location of line card>

This is occurring in load balancing scenario and only affecting ASR9k 1st gen linecards (Trident).
