For DLR only one ospf (uplink) interface is supported - how to override

Jump to solution

Hello mates,

please help to solve the problem:

I have one DLR and two ESGs connected to it via uplink interfaces (both ESGs are also connected to physical infrastructure - different Cisco switches).

I need to run OSPF between DLR and ESG1 as well as between DLR and ESG2.

But OSPF can be enabled only on single DLR Uplink Interface (then I try to enable OSPF on the second uplink I get the error "for logical router only one ospf (uplink) interface is supported").

As I understand this is known limitation, but how can I manade to it?

Thanks.

What you usually do in this situation is having a common transport network to connect ESG to DLR

In this scenario you can even work with ECMP if you need it and will be much more simple I think, and also, you will be able to have multiple neighboards

Yes you can easly use one logical switch connected to both ESGs with the DLR.
