ospf stuck in init state

waqas — Thu, 02 Mar 2017 00:29:00 GMT

ospf v2 created on 2 BD switches for communication between BD switch and Node. Point to point works okay on one BD, but didn't work on other BD side stack its in INIT stage while on Node end its is completely down. All configuration verified and observed to be okay and all perameter check/match
done but nothing work.

The os realease on BD is 15.1.3.4 patch 1-8

I had an issue where one of my switches was stuck in init stage and I bounced the port and it came back up.

Hi waqas,

did you check the license on both switches?

You might need to unconfigure and disable OSPF, and then add the configuration from the start. Be sure to configure both side with identical settings, either both with point-to-point interfaces or both without. Please ensure that no switch is configured with an OSPF priority of 0, but without point-to-point (this requires a core license).

Hi Erik,

We have 2 more ospf areas on same switches and they are working fine, the only issue is with 3rd OSPF on switch02 and on switch01 all 3 ospf areas are working fine, below are the areas define on both the switches.

create ospf area 10.0.0.1
configure ospf area 10.0.0.1 stub summary stub-default-cost 10
create ospf area 10.0.0.2
configure ospf area 10.0.0.2 stub summary stub-default-cost 10

create ospf area 10.0.0.8
configure ospf area 10.0.0.8 nssa summary stub-default-cost 10

Delete and re-create the vlan that the OSPF neighborship should be established on with the other side. Moreover i could see currently the os realease on BD is 15.1.3.4 patch 1-8 as per your last conversation here. This is not the supported version at all for the Black Diamond device at present to consider.

Moving forward you can always upgrade these devices to the latest recommended 16.1.3.6 release for their latest patch if possible.
