Known Affected Releases
Symptom: C7600 sends out BGP TCP sync/ack packets with tos 0. Conditions: - It seems that in case the opposite side router starts the BGP tcp transport connection session, once C7600 received the syc packet, it returns ack with ToS 0. - If C7606 starts the tcp connection session , this issue does not show up. - if I remove "mls qos" configure, this issue does not show up. - if I config "mls qos trust dscp" on the interface, this issue does not show up.
