> @Rubueno @wido I gave this another look and it is not going to work. The link local addresses are created on createPod and changing the configurations will break any SVM created after changing the settings. We'll need a more extensive disign. Can you give some input on what a valid scenario for you would be? > > thanks We should move to IPv6 Link-Local at all for the SSVM :-) These addresses with IPv4 aren't needed at all ;-) Makes life much easier, I promise! Anyway, this isn't the biggest problem now. In RFC5549 the IPv4 address 169.254.0.1 is used for routing IPv4 traffic via IPv6, something which you will use when using EVPN+BGP+VXLAN. Therefor you want to change the control CIDR to something else. It's 'stupid' that we allocate a /16 to this as that's not needed at all, a /20 by default should be more then enough. Any existing installations work just fine. Maybe we should just change the default from this /16 to a /20 (169.254.240.0/20) and be done with it for now. -- This is an automated message from the Apache Git Service.
