You must specify the ipv6-prex parameter in hexadecimal using 16-bit values between colons as documented in RFC 2373. You must
specify the prex-length parameter as a decimal value. A slash mark (/) must follow the ipv6-prex parameter and precede the prex-
length parameter.
You must specify the ipv6-address parameter in hexadecimal using 16-bit values between colons as documented in RFC 2373.
The ethernet | tunnel | ve | vrf parameter species the interfaces for which you can remove cache entries. If you specify an Ethernet
interface, also specify the port number associated with the interface. If you specify a VE, VRF, or tunnel interface, also specify the VE,
VRF name, or tunnel number, respectively.
Clearing IPv6 neighbor information
You can remove all entries from the IPv6 neighbor table or specify an entry based on the following:
• IPv6
prex
• IPv6 address
• Interface type
For example, to remove entries for Ethernet interface 1/3/1, enter the following command at the Privileged EXEC level or any of the
CONFIG levels of the CLI.
device#clear ipv6 neighbor ethernet 1/3/1
Syntax: clear ipv6 neighbor [
ipv6-prex / prex-length | ipv6-address | ethernet port | ve number | vrf vrf-name ]
You must specify the ipv6-prex parameter in hexadecimal using 16-bit values between colons as documented in RFC 2373. You must
specify the prex-length parameter as a decimal value. A slash mark (/) must follow the ipv6-prex parameter and precede the prex-
length parameter.
You must specify the ipv6-address parameter in hexadecimal using 16-bit values between colons as documented in RFC 2373.
The ethernet | ve | vrf parameter species the interfaces for which you can remove cache entries. If you specify an Ethernet interface,
also specify the port number associated with the interface. If you specify a VRF or VE, also specify the VRF name or VE number
respectively.
Clearing IPv6 routes from the IPv6 route table
You can clear all IPv6 routes or only those routes associated with a particular IPv6 prex from the IPv6 route table and reset the routes.
For example, to clear IPv6 routes associated with the prex 2000:7838::/32, enter the following command at the Privileged EXEC level
or any of the Cong levels of the CLI.
device#clear ipv6 route 2000:7838::/32
Syntax: clear ipv6 route [ ipv6-prex/prex-length | vrf vrf-name ]
The ipv6-prex / prex-length parameter clears routes associated with a particular IPv6 prex. You must specify the ipv6-prex
parameter in hexadecimal using 16-bit values between colons as documented in RFC 2373. You must specify the prex-length
parameter as a decimal value. A slash mark (/) must follow the ipv6-prex parameter and precede the prex-length parameter. If you
specify a VRF parameter, specify the VRF name.
