If I remember right, you use "ipv6 enable" if you need link-local
address only, otherwise just assign IPv6 address and you are good to go.
R2#sh ver | in image
System image file is "flash:c2600-j1s3-mz.123-20.bin"
R2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R2(config)#in eth 0/0
R2(config-if)#ipv6 address fec:9:4::4/64
R2(config-if)#do sh run in eth 0/0
Building configuration...
Current configuration : 85 bytes
!
interface Ethernet0/0
no ip address
half-duplex
ipv6 address FEC:9:4::4/64
end
R2(config-if)#do ping ipv6 FEC:9:4::4
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to FEC:9:4::4, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms
