IPv6 prefix authorized by AAA.
RA prefix configured on the interface.
Prefix of the IPv6 global unicast address configured on the interface.
For information about the ND protocol, see Layer 3—IP Services Configuration Guide.
• Method 2—The client requests an IPv6 global unicast address through DHCPv6. The server assigns
an IPv6 address to the client from the address pool authorized by AAA. If no AAA-authorized
address pool exists, DHCPv6 uses the address pool that matches the server's IPv6 address to assign
an IPv6 address to the client. For information about DHCPv6, see Layer 3—IP Services
Configuration Guide.
Method 3—The client requests prefixes through DHCPv6 and assigns them to downstream hosts.
•
The hosts then uses the prefixes to generate global IPv6 addresses. This method uses the same
principle of selecting address pools as method 2.
The device can assign a host an IPv6 address in either of the following ways:
When the host connects to the device directly or through a bridge device, the device can use
•
method 1 or method 2.
When the host accesses the device through a router, the device can use method 3 to assign an IPv6
•
prefix to the router. The router assigns the prefix to the host to generate an IPv6 global unicast
address.
IPv6 DNS server address assignment
On IPv6 networks, two methods are available for the IPv6 DNS address assignment:
• AAA authorizes the IPv6 DNS address and assigns this address to the host through RA messages.
The DHCPv6 client requests an IPv6 DNS address from the DHCPv6 server.

MP overview

Multilink PPP (MP) allows you to bind multiple PPP links into one MP bundle for increasing bandwidth.
After receiving a packet larger than the minimum packet size for fragmentation, MP fragments the packet
and distributes the fragments across multiple PPP links to the peer. After the peer receives these fragments,
it reassembles them into one packet and passes the packet to the network layer.
In addition to increasing bandwidth, MP also provides link-layer load sharing, which can implement
backup. MP fragmentation can reduce transmission delay, especially on low-speed links.
MP is available to all physical or virtual interfaces with PPP encapsulation enabled, including serial,
ISDN BRI/PRI, and PPPoX (PPPoE, PPPoA, or PPPoFR) interfaces. In MP configuration, however, HP
recommends that you include only one type of interfaces in an MP bundle.

Compatibility information

Feature and hardware compatibility

PPP and MP are supported on routers that are installed with an SAE, AS, ASE, BS, E1, E1-F, T1, T1-F, POS,
CPOS, CE3, or AM interface module.
