| It would be nice if we could update the networking.$iface.bundings6 entries to also include binding flags. As an example given the following:
2: en0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 |
link/ether aa:aa:bb:bb:cc:cc brd ff:ff:ff:ff:ff:ff |
inet6 2001:db8::aaaa:bbff:febb:cccc/64 scope global mngtmpaddr dynamic |
valid_lft forever preferred_lft forever |
inet6 2001:db8::1/64 scope global |
valid_lft forever preferred_lft forever |
inet6 fe80::aaaa:bbff:febb:cccc/64 scope link |
valid_lft forever preferred_lft forever
|
'en0' => { |
'bindings6' => [ |
{ |
address => "2001:db8::aaaa:bbff:febb:cccc", |
netmask => "ffff:ffff:ffff:ffff::", |
network => "2620:0:861:103::" |
'scope' => "global" |
'flags' => ['mngtmpaddr', 'dynamic'] |
}, |
{ |
address => "2001:db8::1", |
netmask => "ffff:ffff:ffff:ffff::", |
network => "2620:0:861:103::" |
'scope' => "global" |
}, |
{ |
address => "fe80::aaaa:bbff:febb:cccc", |
netmask => "ffff:ffff:ffff:ffff::", |
network => "fe80::" |
'scope' => "link" |
} |
]

The flags are useful when deciding which addresses to configure daemons to bind to. for instance i would not want a daemon to bind to any binding6 which has either the dynamic or temporary Further i think this could be used in determining the network.ip6 fact. for instance we have environment that have static ipv6 addresses as well as a SLAAC address. I think in this instance when there multiple bindings the ones which have flags of mngtmpaddr or dynamic should no be prefered as the primary. however (at least in our environment) the SLAAC address is perfered

I previously mentioned this in FACT-2843 |
