Hi,

I am evaluating an OSPF solution with bird for IPv4 and IPv6. Tests are 
all working fine.

For IPv4, there is no explicit configuration regarding the router ID (# 
Override router ID #router id 198.51.100.1; works find) required, BIRD as 
other OSPF router simply collects and selects a local IP address (lowest 
or highest value) out of one of the locally existing NIC's addressing.
This is nice, since all of the config's within an OSPF areas might look 
the same and configuration effort is minimized.

Unfortunately, with OSPFv3 for IPv6, this seems not to behave the same, 
therefore configuration effort an a explicit router ID concept  is 
required , when setting up and deploying further IPv6 OSPF routing 
instances.

Can this be solved somehow?


freundlich grüsst,
kind regards,
