Hi,

I'm moving the default gateway from vmbr1 (vlan10, 10.0.10.11, gateway 10.0.10.3) to vmbr9 (vlan100, 10.0.100.11, gateway 10.0.100.3).

The default route is missing.

Before change:

Code: 
# ip route show
default via 10.0.10.3 dev vmbr1 proto kernel onlink
10.0.10.0/24 dev vmbr1 proto kernel scope link src 10.0.10.11
10.0.20.0/24 dev vmbr2 proto kernel scope link src 10.0.20.11
10.0.30.0/24 dev vmbr3 proto kernel scope link src 10.0.30.11
10.0.40.0/24 dev vmbr4 proto kernel scope link src 10.0.40.11
10.0.50.0/24 dev vmbr5 proto kernel scope link src 10.0.50.11
10.0.60.0/24 dev vmbr6 proto kernel scope link src 10.0.60.11
10.0.70.0/24 dev vmbr7 proto kernel scope link src 10.0.70.11
10.0.80.0/24 dev vmbr8 proto kernel scope link src 10.0.80.11
10.0.100.0/24 dev vmbr9 proto kernel scope link src 10.0.100.11
169.254.0.0/16 dev idrac proto kernel scope link src 169.254.0.2
192.168.1.0/24 dev vmbr0 proto kernel scope link src 192.168.1.11

After change:

Code: 
# ip route show
10.0.10.0/24 dev vmbr1 proto kernel scope link src 10.0.10.11
10.0.20.0/24 dev vmbr2 proto kernel scope link src 10.0.20.11
10.0.30.0/24 dev vmbr3 proto kernel scope link src 10.0.30.11
10.0.40.0/24 dev vmbr4 proto kernel scope link src 10.0.40.11
10.0.50.0/24 dev vmbr5 proto kernel scope link src 10.0.50.11
10.0.60.0/24 dev vmbr6 proto kernel scope link src 10.0.60.11
10.0.70.0/24 dev vmbr7 proto kernel scope link src 10.0.70.11
10.0.80.0/24 dev vmbr8 proto kernel scope link src 10.0.80.11
10.0.100.0/24 dev vmbr9 proto kernel scope link src 10.0.100.11
169.254.0.0/16 dev idrac proto kernel scope link src 169.254.0.2
192.168.1.0/24 dev vmbr0 proto kernel scope link src 192.168.1.11

If I go back, the default route comes back again, so it seems it can update it.

What am I missing? Should I do it manually?
