Hi Group,
I thought as soon as you enable ipv6(ipv6 enable command), the etherent interface assigns itself a eui64 format link local address(by appending MAC address associated). But when I enabled ipv6 on the serial interface, I am seeing the link local address same as ethernet. What is the behavior of serial interfaces(They don't have a mac address). Is it ok to enable ipv6(ipv6 enable interface mode command) on the serial interfaces. Pls look at the output. Any feedback with this new technology is appreciated.
