maximum dynamic-routes-ipv6
Specify the maximum number of dynamic (protocol) IPv6 routes a VRF can have.
Syntax maximum dynamic-routes—ipv6 limit {warn-threshold threshold-value | warning-
only}
To remove the limit on the maximum number of IPv6 routes used, use the no maximum dynamic-
routes-ipv6 command.
Parameters
limit Maximum number of IPv6 routes allowed in a VRF. Valid range is from 1 to 8000 (or
maximum allowable for that platform if smaller value).
warning-
threshold
Warning threshold value is expressed as a percentage of the limit value. When the
number of IPv6 routes reaches the specified percentage of the limit, a warning
message is generated. Valid range is 1 to 100. When warn-threshold is used, once
the limit is reached, additional routes will not be allowed into the RTM ( route table
manager ) itself.
warning-only When the warning-only option is used, a syslog message will be thrown when
maximum number of dynamic IPv6 routes reaches the limit. Additional dynamic IPv6
routes will still be allowed.
Defaults No limit is set on the maximum number of dynamic IPv6 routes for a VRF.

Information
If the maximum IPv6 route limit is not specified for a VRF (valid range is from 1 to 8000), then it has
unlimited space that extends to the maximum number of entries allowed for the system. This command is
not applicable to the default and management VRFs.
