Comprehensive and Detailed Explanation From Exact Extract:

From Nokia 7750 SR OS Routing Protocols Guide (Router ID Selection):

“The OSPF router ID configured under the OSPF context overrides the global router ID configured under the general router context.”

Since "configure router ospf router-id 10.10.10.99" was applied, this takes precedence for OSPF operation, even though "configure router router-id 10.10.10.66" was configured globally.

Thus, router R1 will see router R2’s OSPF router ID as 10.10.10.99.
