Hello,

I had problems setting up ipv6 over ospf

show ipv6 route ospf doesn't show any result.

here is my config:

You have enabled IPv6 OSPF on loopback interfaces. Ipv6 is not configured on physical interfaces. You haven't configured physical interfaces for participating in ospf, where are we expecting adjacency, no ospf configurations on the interfaces.

 Please check.

In the future, please use the code feature when posting configs.

While you have IPv4 connections between some of the routers, you don't have any IPv6 addresses defined on those links nor do you have OSPFv3 configured on the links.

It also appears that you're doing multi-area OSPF so don't forget that all ABR's need to have a connection to the backbone area (area 0).  Or you could simplify things and just do single-area OSPF.

Yes But I want to run IPv6 over IPv4

Links between routers should remain in IPv4

only Loopbacks have IPv6 ip addresses

To run, ipv6 over ipv4, we need to have the tunnel interface, right.

What exactly are we trying to achieve.

We can do GRE tunnel between r2 and r3 to make discontigous areas contigous, all areas must connect to area 0.

Virtual link will only work if its only ospfv2 or orly ospfv3. Not a mix of both.

Ok,

here is the idea, everything was done in IPv4, OSPF adjecencies, virtual link etc...

then one day IPv6 came in to the picture and there must be the connectivity, for Labbing, i chose Loopbacks so we still need to keep the connectivity in all the network without removing IPv4 between routers...

you got me now?

Setup an IPv4 GRE tunnel between the routers and do IPv6 inside the tunnel for the OSPF traffic.

This should have everything you need.

Do I have to setup IPv4 OSPF connectivity first then proceed with GRE?


Thanks

I have a question just to make sure i'm doing the right thing:

Should I create a GRE tunnel between R1 and R2 then R1 and R3 then R1 and R4 and so on with the other routers?

I could answer that if I knew the topology.  So if you want to upload a topology diagram, I'd be happy to take a look.

Then yes, you will have to create multiple tunnels since each router has a loopback with an IPv6 address that you're trying to advertise.

I'm still having an issue:

I tried that GRE tunnel between R1 and R2 and vice versa

the ping fails when i try to ping R1's Loopback from R2 or vice versa

I attached a txt file where i have the current configuration.

Is the physical interface up?
Can you ping the other end of the link?
Is the tunnel up? (sho ip int brief)
Can you ping the other end of the tunnel?

Your tunnel is an IPv4 tunnel. You need an IPv6 tunnel.
