…lap check Mirror the APIC PD validation added by aci-apic/mgmt-as-is PR #11881 (CSCwq69622). The APIC rejects any new fvIntersiteConnP / fvIntersiteMcastConnP whose addr falls in the unreserved portion of any fabricExtRoutablePodSubnet pool. On older releases this configuration is allowed and may already be present, but after upgrading the offending MO can no longer be modified, and on a subsequent reconfiguration the upgrade fails to redistribute it. The check mirrors fabric::ExtRoutablePodSubnetBI::checkIfPartOfUnreservedSubnet exactly: for each IPv4 fabricExtRoutablePodSubnet, the unreserved range is [networkStart + reserveAddressCount, networkEnd]. Any fvIntersiteConnP / fvIntersiteMcastConnP whose addr falls in that range on any subnet is reported. IPv6 routable subnets are skipped because the corresponding APIC validation is IPv4-only.
