Asr901-Ecmp-Hash-Config Global-Type - Cisco ASR 901 Command Reference Manual

Chapter 1 CLI Command Reference

asr901-ecmp-hash-config global-type

To specify the equal-cost multi-path routing (ECMP) hashing algorithm at the global level, use the
asr901-ecmp-hash-config global-type command in global configuration mode. To remove this
configuration, use the no form of this command.
Syntax Description hash-crc16-mode

hash-xor1-mode
hash-xor2-mode
hash-xor4-mode
hash-xor8-mode
tunnel-mode

Command Default The hash-crc16-mode algorithm is enabled by default.
Command Modes Global configuration (config)#
Command History Release
15.3(2)S
Usage Guidelines This command is used to configure the ECMP hash configurations for improved load distribution of IP
traffic. The hash-crc16-mode algorithm is enabled by default for ECMP.
Examples The following example shows how to configure the ECMP hash configuration on a Cisco ASR 901
router:
Router# configure terminal
Router(config)# asr901-ecmp-hash-config global-type hash-xor1-mode
Router(config)# asr901-ecmp-hash-config global-type hash-xor1-mode add
OL-26031-07
asr901-ecmp-hash-config global-type {hash-crc16-mode | hash-seed seed-value |
hash-xor1-mode | hash-xor2-mode | hash-xor4-mode | hash-xor8-mode | tunnel-mode} add
no asr901-ecmp-hash-config global-type {hash-crc16-mode | hash-seed seed-value |
hash-xor1-mode | hash-xor2-mode | hash-xor4-mode | hash-xor8-mode | tunnel-mode} add
