ipv6 and subnet router anycast

I have switch DSW1 connected through its fastEthernet interface f0/0 to router R4 fastEthernet f0/0.

Configuring IPv6 on router is successful. When configuring IPv6 on DSW1's interface, it says the following:

DSW1(config-if)#
DSW1(config-if)#ipv6 add 2026::2:2/122 eui-64
%FastEthernet0/0: Warning: 2026::2:0/122 is a Subnet Router Anycast
DSW1(config-if)#

any idea?

Hi,

When you use EUI-64 option, you need to allow 64 bits for host id. So try "ipv6 addr 2026::2:/64 eui-64". This should work.
