Public bug reported:
I encountered an issue where the number of returned networks is unexpected when
combining a provider:network_type filter with the limit parameter.
For example, if there are 2 VLAN networks, filtering with
provider:network_type=vlan&limit=2 returns only 1 network.
To reproduce the issue, you can create 2–3 VXLAN networks, 1 flat
network, and 2–3 VLAN networks.
Demo setup:
public is a flat network
vlan100 and vlan200 are VLAN networks
private and lb-mgmt-net are VXLAN networks
