The RDNSS Lifetime value between two routers seem to not match. This is possible as a transient when configurations are being updated on multiple routes or as a persistent condition because of a misconfiguration in one of the routers
Check the configuration on appropriate routers and make any configuration updates as needed. Locally, configuration can be verified by issuing a 'show router-discovery <vlan-name>'. Configuration can be corrected by one of the 'configure <vlan-name> router-discovery [add|delete] rdnss <ipaddress> {<rdnss_lifetime>}' or 'configure <vlan-name> router-discovery rdnss-lifetime <rdnss_lifetime>' command.
