R0106-HP MSR Router Series Layer 2 - WAN Configuration Guide(V7)

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.

Feature and hardware compatibility

This feature is supported only on SAE, AS, ASE, BS, E1, E1-F, T1, T1-F, POS, CPOS, CE3, CT3, or AM

By default, all interfaces except

Ethernet interfaces, VLAN

interfaces, and ATM interfaces use

PPP as the link layer protocol.

Configuring PPP authentication

You can configure several authentication modes simultaneously. In LCP negotiation, the authenticator

negotiates with the peer in the sequence of configured authentication modes until the LCP negotiation

succeeds. If the response packet from the peer carries a recommended authentication mode, the

authenticator directly uses the authentication mode if it finds the mode configured.
