S4820T
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 specied 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.
