Configuring MLP Bundles and Member Links
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:
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
Step 3
Router(config-if)#
no ppp multilink
Disables multilink for the link.
Step 4
Router(config-if)#
no ppp chap hostname
Removes PPP authentication.

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.
