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