Hi!

I just upgraded a machine to 7.7.1908 and the default route is not being set on boot. This particular server has a bonded interface, and the corresponding configuration for the master is ( /etc/sysconfig/network-scripts/ifcfg-bond0):

TYPE=Bond BOOTPROTO=none DEFROUTE=yes IPV4_FAILURE_FATAL=yes NAME=bond0 DEVICE=bond0 ONBOOT=yes IPADDR=10.3.20.131 PREFIX=24 GATEWAY=10.3.20.1 DNS1=10.3.2.8 BONDING_MASTER=yes BONDING_OPTS="mode=802.3ad xmit_hash_policy=layer2 miimon=100"

The slaves (two of them) are configured like

TYPE=Ethernet BOOTPROTO=none NAME=bond0-slave0 DEVICE=em3 ONBOOT=yes MASTER=bond0 SLAVE=yes

After booting, the routing table is

10.3.20.0/24 dev bond0 proto kernel scope link src 10.3.20.131 metric 300

with no default route configured (manually adding it will work, of course.)

This machine worked perfectly before, and it did during previous upgrades and reboots. Has anyone ever had this problem before?

I have a similar set up to you, and just did the upgrade to 1908, I didn't experience the problem you had, I can't see anything out of the ordinary in your network files.

I originally set up my bond using nmtui

Here is my configuration:

#Bond:

BONDING_OPTS="ad_select=stable all_slaves_active=0 arp_all_targets=any downdelay=0 fail_over_mac=none lp_interval=1 miimon=100 min_links=0 mode=802.3ad num_grat_arp=1 num_unsol_na=1 primary_reselect=always resend_igmp=1 updelay=0 use_carrier=1 xmit_hash_policy=layer2" TYPE=Bond BONDING_MASTER=yes PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=none IPADDR=a.b.c.249 PREFIX=24 GATEWAY=a.b.c.1 DNS1=a.b.d.253 DNS2=a.b.d.4 DNS3=a.b.d.12 DOMAIN=redacted.net DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes NAME="Bond connection 1" UUID=4ccacb42-dfad-484f-8168-b78c70a66c8d DEVICE=nm-bond ONBOOT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_FAILURE_FATAL=no IPV6_ADDR_GEN_MODE=stable-privacy
