I would assume it means 2001::IPV4::HEX::/64

Subject: IPv4-Compatible IPv6 Address

Hi Group,

A task states:

~~~ Configure the Frame Relay networks to use Compatible Addressing with the
IPv4 networks ~~~

I suppose it means IPv4-Compatible IPv6 Address.

So, if the IP address is 172.17.24.2/30, the IPv6 address would be
::AC11:1802

I got the following error message when configuring it on the router using
126-bit mask:

R4(config)#int s 0/0
R4(config-if)#ipv add ::AC11:1802/126
% ::172.17.24.2/126 can not be configured on Serial0/0, invalid

However it accepts "ipv6 address ::1:AC11:1802/126". Does this correctly
answer the task?

Please shed some light on the issue.

Thank you.

B.Rgds,
Lim TS
