To configure OSPF between routers R1 and R2 using IPv6 addresses, you need to use OSPFv3, which supports IPv6. The router ID in OSPFv3 is still a 32-bit number, similar to OSPFv2. Therefore, configuring a 32-bit router ID under the [edit routing-options] hierarchy is necessary. Additionally, you must issue the set protocols ospf3 area 0.0.0.0 interface ge-0/0/1.0 command to enable OSPFv3 on the interface connecting R1 and R2.
BD is correct. ipv6 router-id has never been 128 bit. It's always 32 bit just like ipv4
BD is correct. Router ID is 32 bit here.
IPv6 address is 128 bit
BD for sure!
