• Number Resources
IANA coordinates the global pool of IP and AS numbers, providing them to
Regional Internet Registries.
• Protocol Assignments
Internet protocols’ numbering systems are managed by IANA in conjunction
with standards bodies.
LAUNCH DHCP6C FOR PREFIX DELEGATION (IAPD)
An Identity Association for Prefix Delegation (IAPD) is a collection of prefixes
assigned to a requesting device. A requesting device may have more than one IAPD;
for example, one for each of its interfaces.
A prefix-delegating router (DHCPv6 server) selects prefixes to be assigned to a
requesting router (DHCPv6 client) upon receiving a request from the client. The
server can select prefixes for a requesting client by using static and dynamic
assignment mechanisms. Administrators can manually configure a list of prefixes
and associated preferred and valid lifetimes for an IAPD of a specific client that is
identified by its DUID.
When the delegating router receives a request from a client, it checks if there is a
static binding configured for the IAPD in the client’s message. If a static binding is
present, the prefixes in the binding are returned to the client. If no such binding is
found, the server attempts to assign prefixes for the client from other sources.
An IPv6 prefix delegating router can also select prefixes for a requesting router
based on an external authority such as a RADIUS server using the
Framed-IPv6-Prefix attribute.
LAUNCH DHCP6C FOR RAPID COMMIT
Rapid-Commit; is the process (option) in which a Requesting Router (DHCP Client)
obtains "configurable information" (configurable parameters) from a Delegating
Router (DHCP Server) by using a rapid DHCPv6 two-message exchange. The
messages that are exchanged between the two routers (RR and DR) are called the
DHCPv6 "SOLICIT" message and the DHCPv6 "REPLY" message.
FIXED MTU
Fixed Maximum Transmission Unit. The size (in bytes) of largest protocol data unit
which the layer can pass onwards. This value is 1500 for PPPoA.
ENABLE PPP MANUAL MODE
Use this button to manually connect/disconnect PPP sessions.
ENABLE PPP DEBUG MODE
When this option is selected, the system will put more PPP connection information
into the system log. This is for debugging errors and not for normal usage.
ENABLE MLD MULTICAST PROXY
Multicast Listener Discovery (MLD) is a component of the Internet Protocol Version
6 (IPv6) suite. MLD is used by IPv6 routers for discovering multicast listeners on a
directly attached link, much like IGMP is used in IPv4. The protocol is embedded in
ICMPv6 instead of using a separate protocol.
ENABLE MLD MULTICAST SOURCE
Click to allow use of this WAN interface as Multicast Listener Discovery (MLD)
multicast source.
