for example,
Long Ping Test:
PC1 (192.168.10.88,vlan 100)
ping to
PC2 (192.168.10.89,vlan100)
Normal Path: PC1->2960x->ASR02->DC1 CSW---->DC2 CSW->ASR01->2960x->PC2
When DC1 ASR02 WAN Link(Join interface)/ either etherchannel goes down, active vlan on ASR02 will switches to ASR01, At the same time,
Then, there are around 150 packets loss pinged from PC1 to PC2 when the one of the above links goes down (and 150 packets loss when AED active vlans are resumed on ASR02)
I found out the mac address on 2960s was sticked on ASR02, even ASR02 are down.
But the problem (packet loss) will not be happened if the ASR01 is powered off completely.
After adding cmd "switch(config)# mac-address-table aging-time seconds [ vlanvlan_id ]"on LAN switch 2960x, like mac-address-table aging-time 10 ,
cke the packet loss will be improved to 6 (from 150).
Under this OTV design, Do you have any suggestions for LAN switch to update mac address table if one ASR is down?(Without setting mac aging time on switch) Many Thanks.
