We are experiencing packet loss when ping from PE1 to CE2 when the traffic above 7.2Mbps.
CE1 - PE1 - PE2 - CE2
Type of point-to-point between PE2 and CE2 is 4x E1 multilink (bandwidth 8192Kbit).
Note*** (PE1 to PE2 no packet loss)
We do see the Total output drops keep increasing even the traffic is low. Is it a normal behavior or does this caused the packet loss when PE1 ping to CE2?
Also, what is the maximum throughput can the 4x E1 multilink handle without any packet loss?
