Volume 4-ECMP / Chapter 24-ECMP Configuring ECMP Configuring ECMP Use the command to configure the ECMP route load-balancing algorithm. The algorithm may take some bits from source IP address directly. Or take some bits from a CRC32 calculation result which bases on source IP address and, optionally, the destination address ot TCP/UDP port. Use the no form of the command to reset to the default setting. Use the no command to remove the ecmp loadbalance configuration. Then the ecmp load-balance will go back to default. Command ip route ecmp load-balance [{crc32-lower | crc32-upper} [dip] [port]] no ip route ecmp load-balance Explanation The source IP address is always the calculation base. The ip route ecmp load-balance command is setup for the whole system. Users can use the show ip route ecmp loadbalance command to display the ECMP setting. The ip route ecmp load-balance command without any parameters will only use the load-balance algorithm with the least significant number of bits in the IP address without CRC32 calculation. Use the no form of this command to disable ecmp. This example shows how to set the ecmp algorithm to use the lower few bits if source IP address only: DGS-6600#configure terminal DGS-6600(config)#ip route ecmp load-balance This example shows how to set the ecmp algorithm to use the upper few bits of CRC32 result which bases on the source IP and destination IP addresses: DGS-6600#configure terminal DGS6600(config)#ip route ecmp load-balance crc32-upper dip DGS-6600 Configuration Guide 249
