Cisco Hdlc Protocol - Nokia IPSO 4.0 Reference Manual

connected to the backbone area. Both Nokia Platform B and Nokia Platform C are configured
with IP addresses (10.10.10.2 and 101.10.10.1 respectively).
The interfaces that comprise the virtual link between Nokia Platform A and Nokia Platform C
are both configured as unnumbered. This link will fail because OSPF does not support a virtual
link that uses an unnumbered interface on either end of the link.
more information see RFC 2328. Any virtual link that uses OSPF must have an IP address
configured on both ends. The virtual link between Nokia Platform B and Nokia Platform C
functions because each Nokia Platform is configured with an IP address.
