Re: Router-ID & BGP address-family questions

Well, I certainly haven't encountered EIGRPv6 in the real world and
the code I'm running in my current lab setup doesn't support it, so
perhaps I am mistaken. My old notes from R&S lab prep state that the
'router-id' command is required under the EIGRPv6 process, regardless
of whether or not any interfaces have been assigned IPv4 addresses.
It wouldn't be the first time one of my notes was either just flat out
incorrect or had become OBE over the past few years...
