OSPFv3

[vailedcornet]

"Hello, I'm trying to configure OSPFv3 between two Cisco routers, but IPv6 connectivity is still not working. I simply can't find the problem. On the first router, I have a Router ID of 1.1.1.1 and on the second router, the Router ID is 2.2.2.2. The configuration on both routers includes OSPFv3 in Area 0. Can anyone help me find the error or advise me on what to check? Thank you!"

Hi @vailedcornet ,

You configured the same link local address (fe80::1) on both routers. This will make it impossible for ospfv3 to establish the neighbor relationship.

Please change the link local address on the ISP-Router and it will fix the issue.

ISP-Router:

int gi0/0/0

ipv6 address FE80::2 link-local

Regards,

Thank you for your help!
