Routing router ipv6

Ragounee
Beginner

Hello,

As part of my project, I have to carry out a routing between my routers in IPV6

 

Cisco P7-2.PNG

I made it in ipv4 with dynamic routing unfortunately I can't reproduce it in IPV6
Here is my dynamic configuration in ipv4:


conf
eigrp 100 router
no auto-summarize
network 0.0.0.0
go out

I do not know if it is not compatible with ipv6 or if it is necessary to make another order I am a beginner in routing and I have never done ipv6


I tried anyway to make a static routing which was a big failure, here are my tests:
On Router C:


IPv6 Route 2001:0:CAFE:1::4/127g0/0/2
IPv6 route 2001:0:CAFE:1::6/127 S0/1/0


In this configuration my router C communicates by ping:


Ping 2001:0:CAFE:1::6 100% received
        2001:0:CAFE:1::4 100% received


However when I continue to configure my routes (still on Router C)


IPv6 route 2001:0:CAFE:1::5/127g0/0/0
IPv6 route 2001:0:CAFE:1::9/127 g0/0/1


I test the ping:

Ping 2001:0:CAFE:1::5 0% received
        2001:0:CAFE:1::9 0% received


On previous tests:


ping 2001:0:CAFE:1::4 40/60% received
        2001:0:CAFE:1::6 40/60% received


I do not understand I must very badly configure my routes.


If you have a dynamic router solution in IPV6 I'm interested or guide me to succeed my static routing


Thanks !

Hi @Ragounee ,

The best way would be to enable eigrp for ipv6 as well.

in global configuration mode:

ipv6 unicast-routing

ipv6 router eigrp 100

and under each active interface on all routers

interface xxx

ipv6 eigrp 100

I made your orders as follows:

Router C:

Enable

Conf t

Ipv6 unicast-routing

Ipv6 router eigrp 100

Exit

Interface g0/0/1

Ipv6 eigrp 100

Exit

Interface g0/0/2

Ipv6 eigrp100

Exit

And repeat the process on the other 3 routers under each interface but I still can't ping between them, did I do the commands wrong?

Thank you

Hi @Ragounee ,

This command is wrong. Should be a space between eigrp and 100:

Interface g0/0/2

Ipv6 eigrp100 ++++++> should be ipv6 eigrp 100

Could you please provide the packet tracer file. You need to zip it before you can attach it.

Regards,

HI

Indeed I forgot to write the space but I did it well during my test, I have just done it again without success, I send you the file hoping that this is what you wanted

thank you

Hi @Ragounee ,

It looks like the eigrp process is shutdown by default. You need to configure the following on all 4 routers:

ipv6 router eigrp 100

no shutdown
