Hello,
I'm trying to set up a DHCPv6 stateful. The commands I'm running are:
ipv6 unicast-roting
ipv6 dhcp pool cisco
domain-name example.com
dns-server 1111::FFFF
prefix-delegation pool cisco lifetime 3600 3600
exit
interface GigabitEthernet 0
ipv6 enable
ipv6 address 2001:db8:1:1::1/64
ipv6 address FE80::1 link-local
no shutdown
ipv6 local pool cisco 2001:db8:1:1::/64 64
interface GigabitEthernet 0
ipv6 dhcp server cisco
ipv6 nd managed-config-flag
My problem is at "ipv6 local pool cisco 2001:db8:1:1::/64 64" command.
I get error: % Pool is already reserve
As far as I know, to avoid this error, you need to assign the IPv6 addresss to the interface before set the pool, because the IP of the interface is in the pool of DHCP, so you assign the IP before. If you define the pool first and then the IP of the interface, you get another error saying more or less the same.
I did try this configure on various routers in packet tracer, In 4 of them I got this error, but I succed with 1 (I don't remember the model). Im with a fisical Cisco 800 now.
So is the commands order bad or where is the problem?
P.S: Sorry for my english
