Hi Anshuk,
Eui-64 address means we are telling the interface to calculate its IPV6
address itself provided the network portion specified by you.
E.g.
Int e0/0
Ipv6 add 2001:11:22:33::/64 eui-64
It calculates its address as 2001:11:22:33:xxxx:xxFF:FExx:xxxx/64
And we do this if we don't want the hosts' addresses to be manually
assigned.
And if
Int e0/0
pv6 add 2001:11:22:33::1/64
It will remain the same as specified and wont append the Mac address and
all.
HTH
Gops

Subject: eui-64 in IPV6 address(When to use)
Importance: Low
Hi all,
I have seen in various labs that when the task states to use the network
2001:11:22:33::/64 say on R1 the SG has shown using both as answers. I
can't remember which one had the non eui-64. This is confusing. Taking
the lab shortly. Would this be a proctor type question I could ask?
*2001:11:22:33::/64 eui-64
2001:11:22:33::1/64**
*
My question is when nothing is specified which one should i use.
Any help to provide insight is most welcome.
Regards
Anshuk
