Adding on X670G2 to an existing OSPF network

[JohanHendrikx]

The OSPF network is a X460-24t and two cisco routers. all configured in the same area.

The fimrware of the X460 and the X670 is 16.1.2.14.

But for some reason the X670 is not learning or distribute any route.

How can I troubleshoot this ?

Hi, did you have any log messages? any errors on the link? if you have/had a L1 issue (transceiver, fiber) you might have crc errors preventing the session to be established.

From what I can read in this post, the low layer troubleshooting has not been done. Always start with it.

After the ping the INIT state is changed in the Full state. So it seems that the problem is spontaneously disappeared.

What would be the next step of debugging?

[Parthiban_V]

No Johan. Just to check the reachability i asked you to try a ping. If Ping fails, for sure OSPF will not establish its neigborship.

If there is no issue in reachability and OSPF still stays in INIT state we could have went to the next step of debugging.

I can ping the ipaddress 144.2.144.251

When I look at the OSPF neighbors I see:

192.168.178.63 10 FULL /DR 02:03:22:31/00:00:00:01 144.2.144.251 GIDAT None

The routes are learned now. (?). Was the ping the solution ?

Hi Johan,
From your "show ospf interface" output i could see you have configured a broadcast network through the vlan "GIDAT".

Please provide the following details for both x460 and x670 for the further debugging.

show ospf interface
show ospf interface detail
show ospf neighbor
show configuration ospf
