I am very new to networking and playing around with GNS3. I am trying to configure a router to have 2 IPv6 addresses in a single interface (as far as I understood, this is possible with IPv6)
I managed to add the IPv6 address 2001:CAFE:DEA::25/64 with the following command
R1#enable R1#config ter R1(config)#ipv6 unicast-routing R1(config)#int Ethernet0/0 R1(config-if)#ipv6 address 2001:CAFE:DEA::25/64
However, immediately afterwards, I try to add another, abbreviated IPv6 address
I just type the command (immediately after typing the last one above)
R1(config-if)#ipv6 address Fe80::1
but I get the error message
What am I missing here?
