Description:
In the following two scenarios, packets may get dropped by the BIG-IP device. - [client MTU 1500]<--->(vlan1)<--->[MTU 1500BIG-IP MTU 9000]<--->(vlan2)<--->[MTU 1500server] If the response from the server is large enough to be fragmented, the BIG-IP system is not able to process the packets. - [client MTU 1500]<--->(vlan1)<--->[MTU 1500BIG-IP MTU 9000]<--->(vlan2)<--->[MTU 9000server] Large response coming in a single packet is not fragmented properly on the client-side, then packets may be dropped. ... Impact ... Packets are dropped, traffic is disrupted. ... Conditions ... DHCPv6 MTU size is greater than or equal to 1500. ... Workaround ... None
