Applications
Enable DHCPv6 The Router Advertisement Daemon (radvd) is an open-source software product that
Server or RADVD implements link-local advertisements of IPv6 router addresses and IPv6 routing
prefixes using the Neighbour Discovery Protocol (NDP) as specified in RFC 2461. The
Router Advertisement Daemon is used by system administrators in stateless auto-
configuration methods of network hosts on Internet Protocol version 6 networks.
When IPv6 hosts configure their network interfaces, they broadcast router solicitation
(RS) requests onto the network to discover available routers. The radvd software
answers requests with router advertisement (RA) messages. In addition, radvd
periodically broadcasts RA packets to the attached link to update network hosts. The
router advertisement messages contain the routing prefix used on the link, the link
maximum transmission unit (MTU), and the address of the responsible default router.
Stateless IPv6 hosts can configure themselves automatically when connected to a routed IPv6
network using Internet Control Message Protocol version 6 (ICMPv6) router discovery
(for DHCPv6
messages.
Server)
This type of configuration is suitable for small organizations and individuals. It allows
each host to determine its address from the contents of received user advertisements.
It makes use of the IEEE EUI-64 standard to define the network ID portion of the
address.
Stateful This configuration requires some human intervention as it makes use of the Dynamic
Host Configuration Protocol for IPv6 (DHCPv6) for installation and administration of
(for DHCPv6
nodes over a network.
Server)
The DHCPv6 server maintains a list of nodes and the information about their state to
know the availability of each IP address from the range specified by the network
administrator.
Enable MLD Select whether to enable or disable MLD Snooping on the router. The Multicast
Snooping Listener Discovery (MLD) snooping function constrains the flooding of IPv6 multicast
traffic on LANs on the router.
