Configure DAG IPv6 prefix length from the CLI
You can configure the DAG IPv6 prefix length from
the chassis partition CLI. DAG IPv6 prefix length is a configuration field on each
tenant that is used by disaggregator algorithms as a networking mask. The valid
configuration value is from 1 to 128. The default value is 128. You can configure the
value from either the chassis partition or the tenant.
When you
configure the value at the chassis partition level, it is pushed automatically to
the tenant. When you configure the prefix length at the tenant level, future
configuration at the chassis partition level is disabled and must be re-enabled
from the tenant.
- Log in to the command line interface (CLI) of the chassis partition using an account with admin access.When you log in to the system, you are in user (operational) mode.
- Change to config mode.configThe CLI prompt changes to include(config).
- Configure DAG IPv6 prefix length while creating a tenant.This propagates the value to the tenant. For more information, see Create and deploy tenants from the CLI.
- Configure DAG IPv6 prefix length from the system after the tenant is created.This propagates the value to the tenant.tenants tenant <tenant-name> config dag-ipv6-prefix-length <value>This example changes the DAG IPv6 prefix length of a tenant named "velos-bigip" to 120.default-1(config)# tenants tenant velos-bigip config dag-ipv6-prefix-length 120
- Commit the configuration changes.commit
If you configure the DAG IPv6 prefix length, but
the value is not propagated to the tenant, you might have previously configured this
value externally (such as from the tenant's webUI, CLI, or REST APIs). This disables
configuration at the chassis partition level. On a BIG-IP tenant, run this command
sequence to re-enable
configuration:
tmsh mod sys db dag.userconfigipv6prefixlen value false
