{ MS-CHAP-V2 supports password changing. If the supplicant fails authentication because of an

expired password, it will send the new password entered by the user to the authenticator for

reauthentication.

Multilink PPP (MP) enables you to bind multiple PPP links into one MP bundle for increasing bandwidth.

After receiving a packet that is larger than the minimum packet size for fragmentation, MP fragments the

packet and distributes the fragments across multiple PPP links to the peer end. After the peer end 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.

To sum up, MP delivers the following benefits:

• Increased bandwidth

• Load sharing

• Backup

• Reduced delay through fragmentation

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, it is

preferred that an MP bundle include only one type of interface.
