A vSphere administrator added a new interface to a Distributed Router with a subnet of
172.16.10.0/24 and wants to make this subnet reachable to the rest of the network. How can the
vSphere administrator achieve this?
A.
Enable OSPF on the Distributed Router. Configure the uplink interface in the Backbone area
and redistribute into OSPF the 172.16.10.0/24 subnet.
B.
Enable OSPF in the Distributed Router. Configure the uplink interface in the normal area and
the new interface with the subnet 172.16.10.0/24 in a Backbone area.
C.
Enable OSPF on the Distributed Router. Configure the uplink interface in the Backbone area
and redistribute from OSPF the 172.16.10.0/24 subnet.
D.
Enable OSPF on the Distributed Router. Configure the uplink interface in the Backbone area
and the new interface with the subnet 172.16.10.0/24 in a normal area.

On a DLR, you can only put the uplink interface in an OSPF area. Rejected if you try to put an internal interface into an OSPF area. So, you will have the uplink and a redistribution of the subnet into OSPF.

I would agree with jdoe, only one dynamic routing interface is supported on the DLR.
Answer A seems right to me.

From my point of view the correct answer is
Enable OSPF on the DLR, configure the uplink interface (which should be connected to the ESG) into normal area (the 2 options are Noraml, or NSSA), then redistribute the new subnet into OSPF.

However maybe from VMware point of view the backbone area is normal area and in this case maybe A is the correct answer

Answer is D. No need to redistribute directly connected LIF.

Agree with clement, you cannot redistribute subnet as a declaration, only interfaces.

According to page 104 of the Installation Guide, the correct answer is A.
