Summary     : A Router Advertisement daemon
Description :
radvd is the router advertisement daemon for IPv6.  It listens to router
solicitations and sends router advertisements as described in "Neighbor
Discovery for IP Version 6 (IPv6)" (RFC 2461).  With these advertisements
hosts can automatically configure their addresses and some other
parameters.  They also can choose a default router based on these
advertisements.

Install radvd if you are setting up IPv6 network and/or Mobile IPv6
services.
