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?
