Brajesh,

with duplicate address, very strange.

3620_R3(config-if)#ipv6
*Mar 5 17:52:45.535: %IPV6-4-DUPLICATE: Duplicate address
FE80::204:4DFF:FE06:AAF1 on Et0
3620_R3(config-if)#do sh run int e1/0
Building configuration...
Current configuration : 90 bytes

ip address 198.11.11.3 255.255.255.0

end
Regards,
Nisha
