asr901-ecmp-hash-config global-type
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.
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
Syntax Description
Command Default The hash-crc16-mode algorithm is enabled by default.
Command Modes Global configuration (config)#
Command History
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
hash-crc16-mode Enables hash CRC-16 modes.
hash-seed Enables hash seed value for hash computation.
seed-value Hash seed value.
hash-xor1-mode Enables hash XOR1 mode.
hash-xor2-mode Enables hash XOR2 mode.
hash-xor4-mode Enables hash XOR4 mode.
hash-xor8-mode Enables hash XOR8 mode.
tunnel-mode Enables tunnel mode to look into the inner header for tunneled packets.
add Adds hash mode.
Release Modification
15.3(2)S This command was introduced on the Cisco ASR 901 Series Aggregation
Services Routers.
