Chapter 22 Configuring Multilink Point-to-Point Protocol Connections Configuring MLP Bundles and Member Links Step 3 Step 4 Command Router(config-if)# no ppp multilink Router(config-if)# no ppp chap hostname Purpose Disables multilink for the link. Removes PPP authentication. Changing the Default Endpoint Discriminator When the local system negotiates using MLP with the peer system, the default endpoint discriminator value provided is the username that is used for authentication. The ppp chap hostname or ppp pap sent-username command is used to configure the username for the interface or the username defaults to the globally configured hostname. To change the default endpoint discriminator, enter the following command in interface configuration mode: Command Router(config-if)# ppp multilink endpoint {hostname | ip ip-address | mac lan-interface | none | phone telephone-number | string char-string} Purpose Overrides or changes the default endpoint discriminator the system uses when negotiating the use of MLP with the peer system. hostname indicates to use the hostname configured for the router. This is useful when multiple routers are using the same username to authenticate, but have different hostnames. ip ip-address indicates to use the supplied IP address. mac lan-interface indicates to use the specified LAN interface whose MAC address is to be used. none causes negotiation of the Link Control Protocol (LCP) without requesting the endpoint discriminator option, which is useful when the router connects to a malfunctioning peer system that does not handle the endpoint discriminator option properly. phone telephone-number indicates to use the specified telephone number. Accepts E.164-compliant, full international telephone numbers. string char-string indicates to use the supplied character string. Configuration Example for Changing the Endpoint Discriminator Example 22-4 shows how to change the MLP endpoint discriminator from the default CHAP hostname C-host1 to the hostname cambridge. Example 22-4 Changing the Default Endpoint Discriminator Router(config)# interface multilink 8 Router(config-if)# ip address 10.1.1.4 255.255.255.0 Router(config-if)# ppp chap hostname C-host1 Router(config-if)# ppp multilink endpoint hostname cambridge OL-2226-23 Cisco 10000 Series Router Software Configuration Guide 22-37
