http://bugzilla.opensuse.org/show_bug.cgi?id=1205247 Bug ID: 1205247 Summary: eth0 may not get a default route when eth1 is configured for same subnet Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.4 Hardware: x86-64 OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Network Assignee: screening-team-bugs@suse.de Reporter: kruse@pre-sense.de QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- If I configure a system with 2 NIC's in the same subnet, the default route will not be set reliantly. How to reproduce: Install openSUSE Leap 15.4 via netinstaller (openSUSE-Leap-15.4-NET-x86_64-Build243.2-Media.iso) in a VM with 2 NIC's: When prompted for a system role choose "Server". When partitioning screen shows up, make sure btrfs is used (should be the default). In the final screen, make sure "wicked" is used as the networking service, click "Network Configuration" and configure eth0: In Address tab set a static IP (e.g. 192.168.200.44) with subnet mask "/24" and configure eth1 to use a static IP in the same subnet (e.g. 192.168.200.34/24). Set device activation to "On Cable Connection" for both interfaces. Add a generic (not bound to a specific NIC) default route (gateway), that is in the same subnet (e.g. 192.168.200.1) Go on with the installation ... In the booted system, check if you got a route on eth0 (e.g. with `ip route`). List the contents of /etc/sysconfig/network with `ls -Ul` (-U means "unsorted"). If you have a route on eth0, ifcfg-eth0 will be listed before ifcfg-eth1, if eth0 has no route, ifcfg-eth1 will be listed first instead. The listing order can be changed by creating a NEW directory and create the desired config FIRST, like so: -- systemctl stop wicked cd /etc/sysconfig/ mkdir network_new cp network/ifcfg-eth0 network_new/ cp -r network/* network_new/ mv network network_old cp -r network_new network systemctl start wicked -- `ls -U1 network_*` will give output similar to /etc/sysconfig/network_old: if-down.d if-up.d providers scripts ifcfg-lo ifcfg.template config dhcp routes ifcfg-eth0 ifcfg-eth1 /etc/sysconfig/network_new: ifcfg-eth1 config dhcp ifcfg-eth0 ifcfg-lo ifcfg.template if-down.d if-up.d providers routes scripts -- contents of ifcfg-eth0: IPADDR='192.168.200.44/24' BOOTPROTO='static' STARTMODE='ifplugd' ZONE=public ---- 1. Why don't I get a route on eth0 in the original scenario, even if eth1 has no carrier or does not exist at all? 2. Wouldn't it be better for wicked to read the config files in a predictable (alphanumerical) order? -- You are receiving this mail because: You are on the CC list for the bug.
