What is the best way to configure OSPF to inject all 50+ SVIs into the
routing domain?
Would you configure network statements for all SVI networks and passive the
interfaces?
Would you configure OSPF on the uplink interfaces only and redistributed
connected to create type-5 externals?
If it were me, the SVIs would be announced into BGP, so that my OSPF
world stayed small and clean.
That said, remember that the network statement(s) only have to match,
through wildcard math, the _IP addresses_ of the interfaces to be
included in OSPF. If you run a single area, 'network 0.0.0.0
255.255.255.255 area 0' is all you need. Flipside, if you want to lock
down OSPF to the point that shifting an interface within a subnet causes
OSPF to drop so you can catch the culprit in the act, 'network
10.20.30.254 0.0.0.0 area 0' matches exactly that one address (but the
interface's correct netmask is used when inserting the route into OSPF).
