IPv6 router advertisements
Beginning with software release K.15.01, the routing switches support IPv6 RA configuration and transmission based on RFC 4861, "Neighbor Discovery for IP Version 6 (IPv6)" and RFC 4862, "IPv6 Stateless Address Autoconfiguration."
IPv6 RAs on a VLAN provide the ND policy the system administrator has configured for devices running in IPv6 host mode with address autoconfiguration enabled. RAs also enable hosts on a VLAN to build a list of default (reachable) routers on that VLAN or tunnel.
