■
Use to enable the IPv6 Neighbor Discovery process on an interface.
■
You can include the following commands in IPv6 profiles to configure Neighbor
Discovery route advertisement characteristics.
Description Command
Enables Neighbor Discovery on an interface ipv6 nd
Specifies IPv6 prefix included in IPv6 router advertisements ipv6 nd prefix-advertisement
■
Example
host1(config)# profile ProfileIpv6South22
host1(config-profile)# ipv6 nd
■
Use the no version to disable the Neighbor Discovery process for the profile.
■
See ipv6 nd
ipv6 unnumbered
■
Use to set up an unnumbered interface.
■
An unnumbered interface does not have an IPv6 address assigned to it.
Unnumbered interfaces are often used in point-to-point connections where an
IPv6 address is not required.
■
This command enables IPv6 processing on an interface without your having to
assign an explicit IPv6 address to the interface.
■
You supply an interface location that is the type and number of another interface
on which the router has an assigned IPv6 address. This interface cannot be
another unnumbered interface.
■
Example
host1(config-if)# ipv6 unnumbered loopback 0
■
Use the no version to disable IPv6 processing on an interface.
■
See ipv6 unnumbered
ppp authentication
■
Use to request authentication from a PPP peer and set the authentication method.
■
The router supports the MD5 authentication algorithm for CHAP authentication.
■
Example 1—Specifies the order of preference for the primary authentication
protocol
host1(config-if)# ppp authentication pap chap eap
The router requests the use of PAP as the authentication protocol (because it
appears first in the command line). If the peer refuses to use PAP, the router
requests the CHAP protocol. If the peer refuses to use CHAP, the router requests
