Can't do that... 0.0.0.0 as an ID is reserved for starting a DR/BDR
election or on a VL/P2P link.
Per RFC 2328:
Designated Router
The Designated Router selected for the attached network. The
Designated Router is selected on all broadcast and NBMA networks
by the Hello Protocol. Two pieces of identification are kept
for the Designated Router: its Router ID and its IP interface
address on the network. The Designated Router advertises link
state for the network; this network-LSA is labelled with the
Designated Router's IP address. The Designated Router is
initialized to 0.0.0.0, which indicates the lack of a Designated
Router.
On unnumbered
point-to-point networks and on virtual links this field should
be set to 0.0.0.0.
HTH,
Scott

No I am wanting to set the router-ID to 0.0.0.0 not the area ID. This is
strictly a lab thing not that I would want to do this in the real world.
Thanks,
