I have this very basic ipv4 network in packet tracer using EIGRP with 3 routers & switches
ipv4 is setup and working correctly. with this on all 3 routers:
router eigrp 1
no auto
passive g0/1
EIGRP router-id 1.1.1.1
network 10.2.2.1 0.0.0.3
network x.x.x.x x.x.x.x
network x.x.x.x x.x.x.x
My goal is to take one link between 2 of the routers and make that IPV6. Then disable an interface on the 3rd router to force packets through the ipv6 link.
I am IPV6 illiterate so need some help.
1: I removed the IPV4 add's on both router interfaces that I want to make IPV6.
2: ipv6 unicat-routing enabled on both routers
3: ipv6 enable enabled on both serial interfaces
I found this list on the Cisco site but still can;t get it working.
enable
2. configure terminal
3. ipv6 unicast-routing
4. interface type number
5. no shut
6. ipv6 enable
7. ipv6 eigrp as-number
8. ipv6 router eigrp as-number
9. router-id ip-address
10. exit
11. show ipv6 eigrp [as-number] interfaces [type number] [detail]
What is needed to change one link to an IPV6 address?
Any help will be greratly appreciated.
Thanks

Thanks for the help everyone.
I managed to get it working. I had to do a shut, no shut on the interfaces then it worked. (both interfaces were green in PT) but did the shut and no shut and bingo.
Thanks again.

Hi David,
First of all, you do not need to disable IPv4 on an interface to configure IPv6. IPv4 and IPv6 traffic can both flow on the same interface in parallel.
The configuration you posted looks like what is needed. What do you see when you do a "show ipv6 eigrp neighbor"?

Hello
As Harold said, you can have both IPV4 IPV6 on your interface.
Start with IPV4 :
int fa 0/0 ip add 192.168.1.2 255.255.255.0 router eigrp 1 EIGRP router-id 2.2.2.2 network 192.168.1.2 0.0.0.0
Then add IPV6 configuration :
ipv6 unicast-routing int fa 0/0 ipv6 address 2001:DB8:0::2/48 ipv6 eigrp 2 ipv6 router eigrp 2 eigrp router-id 6.6.6.2
Neighbors should be up after that :
R1#sho ipv6 eigrp neighbors EIGRP-IPv6 Neighbors for AS(2) H Address Interface Hold Uptime SRTT RTO Q Seq (sec) (ms) Cnt Num 0 Link-local address: Fa0/0 10 00:59:47 55 330 0 4 FE80::C802:EFF:FECC:8
Note that neighbors are using link local add and not global unicast configured to enable adjacency
Hope this helps
