Cisco ACI - OPSF L3out routing issue between 2 neighbor

[mangeshrangari201]

Hello All,

We have created 2 L3Out, one L3out for Legacy to Cisco ACI which is in OSPF area 0. Another OSPF L3out for New Core to Cisco ACI which is in area 1. We are using same border leaf switches for both L3out.

At New Core switch OSPF area 1 is configured.

We are able to ping subnets of legacy switch & Cisco ACI L3 BD subnet from New Core, but we are not able to ping subnets created in New Core switch from Legacy switch.

Please help to resolve the issue

Hi,

Can you draw your topology? Are both L3OUTs in the same VRF?
Can you show:
fabric <LF_ID> show ip route vrf <Tenant:VRF>
fabric <LF_ID> show ip ospf neighbors vrf all

Regards,

Andrzej
