Routed: fix create network exception when auto-allocation is disabled #11624

weizhouapache · 2025-09-12T09:48:22Z

Description

This PR fixes the issue which can be reproduced by steps below

add IPv4 subnet in zone (/20)
create Routed network offering
create a IPv4 subnet (/24)
disable global setting routed.ipv4.network.cidr.auto.allocation.enabled
create a Routed network from the offering with cidr size 24

without this PR: got an error on UI: Internal error executing command, please contact your system administrator

with this PR: the network is created successfully

LGTM. Verification passed.

Verified routed network creation with and without CIDR under different auto-allocation states. Confirmed correct behavior after the fix - manual CIDR works when auto-allocation is disabled, and subnet is auto-assigned when enabled. Tested via API and UI (CIDR not shown in UI but network creation succeeded).

Performed Tests

1. Create IPV4 subnet for zone

(localcloud) 🐱 > createIpv4SubnetForZone zoneid=cc565e94-b5cf-4c4a-8d22-6aeaf5cbe538 subnet=10.10.0.0/20

}

2. Create a routed network offering

5. Disable auto-allocation

(localcloud) 🐱 > update configuration name=routed.ipv4.network.cidr.auto.allocation.enabled value=false
