Explanation:
In OSPFv3 and OSPF version 2, the router uses the 32-bit IPv4 address to select the router
ID for an OSPF process. The router ID selection process for OSPFv3 is described below
(same as OSPF version 2):
1. The router ID is used if explicitly configured with the router-id command.
2. Otherwise, the highest IPv4 loopback address is used.
3. Otherwise, the highest active IPv4 address.
4. Otherwise, the router ID must be explicitly configured.
In this case the router ID 10.1.1.3 is explicitly configured
