Clearing IPv6 routes from the IPv6 route table
You can clear all IPv6 routes or only those routes associated with a particular IPv6 prefix from the IPv6
route table and reset the routes.
For example, to clear IPv6 routes associated with the prefix 2000:7838::/32, enter the following
command at the Privileged EXEC level or any of the Config levels of the CLI.
device#clear ipv6 route 2000:7838::/32
Syntax: clear ipv6 route [ ipv6-prefix/prefix-length | vrf vrf-name ]
The ipv6-prefix / prefix-length parameter clears routes associated with a particular IPv6 prefix. You must
specify the ipv6-prefix parameter in hexadecimal using 16-bit values between colons as documented in
RFC 2373. You must specify the prefix-length parameter as a decimal value. A slash mark (/) must
follow the ipv6-prefix parameter and precede the prefix-length parameter. If you specify a VRF
parameter, specify the VRF name.
Clearing IPv6 traffic statistics
To clear all IPv6 traffic statistics (reset all fields to zero), enter the following command at the Privileged
EXEC level or any of the Config levels of the CLI.
device(config)#clear ipv6 traffic
Syntax: clear ipv6 traffic
Displaying global IPv6 information
You can display output for the following global IPv6 parameters:
• IPv6 cache
• IPv6 interfaces
• IPv6 neighbors
• IPv6 route table
• Local IPv6 routers
• IPv6 TCP connections and the status of individual connections
• IPv6 traffic statistics
Displaying IPv6 cache information
The IPv6 cache contains an IPv6 host table that has indices to the next hop gateway and the router
interface on which the route was learned.
To display IPv6 cache information, enter the following command at any CLI level.
device#show ipv6 cache
Total number of cache entries: 10
IPv6 Address Next Hop Port
1 2001:DB8::2
LOCAL tunnel 2
2 2001:DB8::106
LOCAL ethe 3/2
3 2001:DB8::110
DIRECT ethe 3/2
