Page 10: Configuring Ppp And Mp
Configuring PPP and MP PPP overview Point-to-Point Protocol (PPP) is a point-to-point link layer protocol. It provides user authentication, supports synchronous/asynchronous communication, and allows for easy extension. PPP includes the following protocols: Link control protocol (LCP)—Establishes, tears down, and monitors data links. •...
Page 11: Ppp Authentication
ID by using the MD5 algorithm. It is more secure than PAP. The authenticator may or may not be configured with a username. HP recommends that you configure a username for the authenticator, which makes it easier for the peer to verify the identity of the authenticator.
Page 12: Ppp For Ipv4
MS-CHAP-V2 supports password change. If the peer fails authentication because of an expired password, it will send the new password entered by the user to the authenticator for reauthentication. PPP for IPv4 On IPv4 networks, PPP negotiates the IP address and DNS server address during IPCP negotiation. IP address negotiation IP address negotiation enables one end to assign an IP address to the other.
Page 13: Mp Overview
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.

To set the keepalive retry limit, use the timer-hold retry command. On a slow link, increase the keepalive interval to prevent false shutdown of the interface. This situation might occur when keepalives are delayed because a large packet is being transmitted on the link. To disable sending of keepalives, set the keepalive interval to 0.

Page 54: Configuring Pppoe
Configuring PPPoE Overview Point-to-Point Protocol over Ethernet (PPPoE) extends PPP by transporting PPP frames encapsulated in Ethernet over point-to-point links. PPPoE specifies the methods for establishing PPPoE sessions and encapsulating PPP frames over Ethernet. PPPoE requires a point-to-point relationship between peers instead of a point-to-multipoint relationship as in multi-access environments such as Ethernet.
Page 55: Command And Hardware Compatibility
As shown in Figure 1 1, a PPPoE session is established between each host (PPPoE client) and the • carrier router (PPPoE server). The service provider assigns an account to each host for billing and control. The host must be installed with PPPoE client software. Figure 11 Network structure 2 PPPoE Client Host A...

Page 79: Configuring L2Tp
Configuring L2TP Overview The Layer 2 Tunneling Protocol (L2TP) is a Virtual Private Dialup Network (VPDN) tunneling protocol. L2TP sets up point-to-point tunnels across a public network (for example, the Internet) and transmits encapsulated PPP frames (L2TP packets) over the tunnels. With L2TP, remote users can access the private networks through L2TP tunnels after connecting to a public network by using PPP.
Page 80: L2Tp Message Types And Encapsulation Structure
L2TP message types and encapsulation structure L2TP uses the following types of messages: • Control messages—Used to establish, maintain, and delete L2TP tunnels and sessions. Control messages are transmitted over a reliable control channel, which supports flow control and congestion control. Data messages—Used to encapsulate PPP frames, as shown in Figure 23.
Page 81 Figure 25 NAS-initiated tunneling mode A NAS-initiated tunnel has the following characteristics: The remote system only needs to support PPP, and it does not need to support L2TP. • • Authentication and accounting of the remote system can be implemented on the LAC or LNS. Figure 26 NAS-initiated tunnel establishment process As shown in Figure...
Page 82 The LAC sends the authentication information (username and password) to its RADIUS server (RADIUS server A) for authentication. RADIUS server A authenticates the user and returns the result. The LAC initiates an L2TP tunneling request to the LNS (Device B) when the following conditions exist: The user passes the authentication.
Page 83 A client-initiated tunnel has higher security because it is established between a remote system and • the LNS. The remote system must support L2TP and be able to communicate with the LNS. This causes poor • expandability. As shown in Figure 28, the workflow for establishing a client-initiated tunnel is similar to that for establishing a NAS-initiated tunnel.
Page 84: L2Tp Features
The LNS assigns a private IP address to the LAC instead of to the remote system. • As shown in Figure 30, the workflow for establishing an LAC-auto-initiated tunnel is similar to that for establishing a NAS-initiated tunnel. (Details not shown.) Figure 30 Establishment process for LAC-auto-initiated tunnels L2TP features Flexible identity authentication mechanism and high security—L2TP by itself does not provide...

Page 180: Configuring Ddr
Configuring DDR Overview As shown in Figure 54, routers use dial-on-demand routing (DDR) for the following purposes: • Setting up a dialup connection over PSTN/ISDN when communication needs arise. Tearing down the connection when the communication is complete. • Figure 54 DDR communication process In addition to PSTN/ISDN, Ethernet and ATM use DDR to implement access control.
Page 181 Traditional DDR You can configure traditional DDR by using the following methods: • Configure DDR parameters directly on a physical interface. The router places or receives calls through the physical interface. The physical interface can correspond to one or more call destinations. This method applies when only one interface places or receives calls.
Page 182: Ddr Types
Figure 55 Relationships among physical interfaces, dialer interfaces, and call destinations Bundle DDR is simpler and more flexible than traditional DDR. Bundle DDR separates physical interface configuration and logical configuration for calls and allows one-to-many bindings between dial services and physical interfaces. A physical interface can serve multiple dial services. Figure 56 Relationships among physical interfaces, dialer interfaces, and call destinations DDR types Depending on how DDR calls are triggered, DDR includes packet-triggered DDR, auto-dial DDR, and...
Page 183: Command And Hardware Compatibility
For more information about interesting and uninteresting packets, see "Associating a dial rule with a dialup interface." Auto-dial DDR DDR automatically initiates a dialup connection to the remote end upon router startup without requiring a triggering packet. If the connection cannot be established, it will retry at certain intervals. The established connection will not disconnect due to timeout of the idle-timeout timer.

When the percentage of the traffic rate on a link to bandwidth exceeds the defined load threshold, the system automatically brings up a second link and assigns the two links to an MP bundle. When the percentage of the traffic rate on these two links to bandwidth exceeds the defined load threshold, the system brings up a third link, and assigns it to the MP bundle, and so on.

HP recommends that you configure the dialer threshold, ppp mp max-bind, and ppp mp min-bind • commands on one end of the call. When the configured values are not the same on the two ends of the call, the following values take effect: The smaller threshold value.
Page 195: Configuring The Callback Client

Page 239: Configuring Frame Relay
Configuring Frame Relay This feature is supported only on the following modules: CE3. • CPOS. • CT3. • • E1-F. • • SAE. • • • T1-F. Overview Frame Relay uses statistical multiplexing technology and can establish multiple virtual circuits over a single physical cable to make full use of network bandwidth.
Page 240: Virtual Circuit
As shown in Figure • Router B and Router C form a simple Frame Relay network. DTE devices Router A and Router D are attached to the network. • The interface type DTE or DCE is identified only for the UNI interfaces. A virtual circuit between two DTE devices can be assigned different DLCIs on different segments.
Page 241: Frame Relay Address Mapping
Frame Relay address mapping Frame Relay address mapping associates the protocol address of a peer device with a Frame Relay address (local DLCI). Then, the upper-layer protocol, for example, IP, can locate the peer device. For example, an IP packet is transmitted across a Frame Relay network as follows: When a DTE device receives an IP packet, the DTE device looks up the IP routing table for the outgoing interface and next-hop address.
Page 242 Monitor PVC status changes. • • Verify link integrity. The system supports the following LMI standards: ITU-T Q.933 Annex A. • ANSI T1.617 Annex D. • Nonstandard LMI (compatible with other vendors). • To communicate properly, the DTE and the DCE must use the same type of LMI. LMI messages LMI messages include the following types: Status enquiry message—A DTE sends status enquiry messages regularly to a DCE to request the...

Page 251: Configuring Frame Relay Stac Compression
Configuring Frame Relay STAC compression STAC compression is a payload compression method that applies to Frame Relay packets and InARP packets. STAC compression cannot compress LMI messages. The two ends of a PVC negotiate the PVC state by using STAC control messages after STAC compression is enabled.
Page 252: Configuration Restrictions And Guidelines
Configuration restrictions and guidelines When you configure Frame Relay FRF.12 fragmentation, follow these restrictions and guidelines: • FRF.12 fragmentation and Frame Relay traffic shaping are mutually exclusive on an interface. For more information about Frame Relay traffic shaping, see ACL and QoS Configuration Guide. An MFR interface does not support FRF.12 fragmentation.
