L 22::22/128 [0/0]

via Vlan111, receive C 33::/64 [0/0]

via Vlan111, directly connected L 33::33/128 [0/0]

via Vlan111, receive I1 454::/96 [115/20]

via FE80::4255:39FF:FE89:3F71, Vlan2020

Verifying a Stateless Auto-Configuration

To verify the autoconfigured IPv6 address and its state, use the show ipv6 interface command in privileged EXEC mode, as shown in the example.

Router# show ipv6 interface loopback 0

Loopback0 is up, line protocol is up

IPv6 is enabled, link-local address is FE80::4255:39FF:FE89:4831

No Virtual link-local address(es):

Global unicast address(es):

FE01:4::4, subnet is FE01:4::/64

Joined group address(es):

FF02::1

FF02::2

FF02::5

FF02::1:FF00:4

FF02::1:FF89:4831

MTU is 1514 bytes

ICMP error messages limited to one every 100 milliseconds

ICMP redirects are enabled

ICMP unreachables are sent

ND DAD is not supported

ND reachable time is 30000 milliseconds (using 30000)

ND RAs are suppressed (periodic)

Hosts use stateless autoconfig for addresses.

Verifying IPv6 Implementation on VLAN Interfaces

To verify the IPv6 implementation on VLAN interfaces, use the show ipv6 interface command in privileged EXEC mode, as shown in the example.

Router# show ipv6 interface vlan40

Vlan40 is up, line protocol is up

IPv6 is enabled, link-local address is FE80::4255:39FF:FE89:4831 No Virtual link-local address(es):

Global unicast address(es):

2011:8:8:3::4, subnet is 2011:8:8:3::/64

Joined group address(es):

FF02::1

FF02::2

FF02::5

FF02::6

FF02::1:FF00:4

FF02::1:FF89:4831
