Description (partial)

Due to OSPF "default leak policy" with "Leak default route only" it's expected to have "deny-all" route-map in OSPF process, but another route-map was pushed to OSPF process:
show ip ospf vrf Prod:Internal
Routing Process default with ID VRF Prod:Internal
Stateful High Availability enabled
Supports only single TOS(TOS0) routes
Supports opaque LSA
Table-map using route-map exp-ctx-2850816-deny-external-tag
Redistributing External Routes from
   static route-map exp-ctx-st-2850816
   direct route-map exp-ctx-st-2850816
   bgp route-map exp-ctx-proto-2850816
   eigrp route-map exp-ctx-proto-285081

Inconsistency can be observed among different leafs:
One leaf can have "deny-all" policy (expected)
Another leaf can have non "deny-all" - as per example exp-ctx-proto-2850816

Inconsistency can occur after leaf clean reload/software upgrade due to timing issue - which policy will be pushed to leafs first

2 OSPF L3outs for same VRF/same leaf
One L3out contains "default leak policy" with "Leak default route only"
Another L3out has policy that allows redistribution of some prefixes to OSPF
