http://slidepdf.com/reader/full/cisco-ipv6-configuration-commands 1/10

CISCO IPV6 CONFIGURATION COMMANDS:

Basic Commands:

To enable routing of IPv6 packets – required to enable IPv6 on a router:Router(config)# ipv6 unicast-routing

To enable IPv6 on an interface:Router(config-if)# ipv6 enable

To add an IPv6 address to an interface:ipv6 address <address>/<prefix> [link-local] [eui-6]

To leave the interface unnumbered:ipv6 unnu!bered et" /

IPv6 Enabled Commands:ping ipv6 <ipv6adr>

traceroute ipv6 <ipv6adr>

telnet <ipv6adr>

ss" [-l <userid>] [-c <des$%des>] [-o nu!berofpass&dpro!pts <#>] [-p

<port#>] <ipv6addr> [co!!and]

s"o& ip ss"

ip "ttp server

dns lookup

tftp

Neighbor Discovery:

To adjust the Router Advertisement intervals:ipv6 nc reac"able-ti!e <#>

ipv6 nd ra-interval <#> default is ' seconds

ipv6 nd ra-lifeti!e <#> default is seconds (% !inutes)

ipv6 nd ns-interval <#> default is !illiseconds

ipv6 nd suppress-ra

ipv6 nd !anaged-config-flagipv6 nd ot"er-config-flag

To adjust the lifetimes for the prefi:ipv6 nd prefix-advertise!ent <routing-prefix>/<lengt"> <valid-lifeti!e>

<preferred-lifeti!e> [onlink] [auto-config]

ipv6 nd prefix-advertise!ent *+,,.',/'% autoconfig

!alid lifetime " ho# long the node$s address remains in the valid state – after that it is invalidPreferred lifetime " ho# long the stateless autoconfig address remains preferred – less than or equalto the valid lifetime % If preferred%lifetime " & then this router is not preferred'ff%link " sets the (%bit to ')) – default setting is to have the (%bit set to '*



*o%autoconifg " sets the A%bit to ')) – default setting is to have the A%bit set to '**o%advertise " the specified prefi cannot be used for stateless autoconfiguration – the prefi is notincluded in RA messages – default is to have this flag turned '))

To remove an advertised prefi:no ipv6 nd prefix <ipv6-prefix>

To turn off Router Advertisements:

no suppress-ra

+uplicate Address +etection ,+A+-:ipv6 nd dad atte!pts <#> disabled &it" a setting of 0

Router Redirection:ipv6 redirects
