Unknown Direct Connected route on UDLR

Hello,

I am working with routing between UDLR and ESGs (NSX 6.4.3), I noticed an unknown route record as following:

Show IP route:  shown all connected and dynamic routes, but the weird is the below route:

Noting that UDLR has the following interfaces only:

Show IP address: shown an vNIC with the following subnet:

Can you advise about the role and the reason of this vNIC ? is it normal ?

Thanks in advance,


If my reply was helpful, I kindly ask you to like it and mark it as a solution

Regards,

IP address start with 169.x.x.x is link local address and used for HA communication between EDGE/DLR HA internal link .

You can ignore it for now.

I believe the output above was taken from a DLR deployed with HA enabled, and the HA interface is assigned an IP address. This appears as two IP addresses, 169.254.1.1/30 (auto-assigned for HA).

Foe details please refer : NSX Routing Control Plane CLI
