Does I wrong something in this interfaces between R-R, S-R and H-R (R-router, S-Switch, H-hosts)
And when I try to put command
ipv6 unicast-routing, it's unrecognize, or when just put
ipv6 ? it said that is unrecognize command. It is only in router 2621XM.
And on the side from router0 f0/0/0 can't recognize ipv6 address command. WHY?
