According to Doyle (Vol 1) p.413, "Cisco's OSPF will continue to use a
Router ID learned from a physical interface even if the interface
subsequently fails or is deleted."
Later on p.524, "If a physical interface from which the Router ID was taken
experiences a hardware failure, if the interface is administratively shut
down, or if the IP address is inadvertently deleted, the OSPF process must
acquire a new Router ID. Therefore, the router must prematurely age and
flood its old LSA and then flood LSAs containing the new ID."
These statements appear to be contradictory. I did test in my lab by
changing the IP address of the highest Interface (Router ID), both Loopback
and with no looback on a physical, and the Router ID changed on the fly. So,
the second statement seems to be true. The question is whether the first
statement false or does it apply to a special circumstance?
Thanks.
