That's not considered good design. If you absolutely must have a topology
like this then use an OSPF virtual link. I really wouldn't go down this
road if I was you.

If you wanted to go completely mad you could use hybrid ports on NE2 (both
sides)
NE1 --network-------hybrid--NE2--hybrid--------network--NE3
Use an epipe on the hybrid ports of NE2 for the NE1 to NE3 connectivity and
use and put a router interface on another subinterface:

|------------------------------ospf etc ---------------|
NE1 --.1q 100 ------- NE2epipe --------.1q 100 NE3
|--------.1q 200 -------NE2 network
|-----ospf etc----------------|

quite hard to explain with ascii :)

My advice, redesign your topology.
