Hi Experts,
I'm new to IPv6 and have some doubt on configuration.
I have a 4500 switch which is supposed to get a IPv6 address via dhcp from a linux machine.
On the linux machine I have configured a pool on the /64 prefix and it handsover ip to the 4500 switch.
the problem is: although I have configured /64 prefix on my Linux PC, the switch always gets the IP on the /128 prefix so because of that i'm unable to ping the dhcp server from the client (Switch).
an I doing something wrong with my configuration
My configuration on the switch is as follows:
Switch#sh run int gig1/1
Building configuration...
Current configuration : 100 bytes
!
interface GigabitEthernet1/1
no switchport
ip address dhcp
ipv6 address dhcp
ipv6 enable
end
The logs says the following:
Switch#

Any reason why is it always assigning an ip address from the /128 mask?
Thanks for your help in advance.
