- Use the Layer 4 Source and Destination Ports in the ECMP Hash Key
Use a combination of the Layer 4 source port and Layer 4 destination port, in addition to the combination of the source IP address, destination IP address, protocol, and DSCP field, as the ECMP hash key. Note that this flag should be enabled only in networks where it can be guaranteed that there will never be IP fragmentation. Otherwise, enabling this could lead to out-of-order packets.
Use the Layer 4 source and destination ports in the EMCP hash key:
vEdge(config-vpn-1)# ecmp-hash-key layer4 vEdge(config-vpn-1)# show config vpn 1 ecmp-hash-key layer4 !
