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, _________________________ _________________________ _________________________ _________________________ _________________________ ________________ Arno Odermatt arno.odermatt@ch.schindler.com ****************************************************** Notice: The information contained in this message is intended only for use of the individual(s) named above and may contain confidential, proprietary or legally privileged information.
