[manjaro-general] Routing Issue

[Rainer Dorsch]

Hi,

I hit a strange routing issue:

[n3150 ~]# route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         192.168.0.1     0.0.0.0         UG    1024   0        0 
enp2s0.1
192.168.0.0     0.0.0.0         255.255.255.0   U     1024   0        0 
enp2s0.1
192.168.2.0     0.0.0.0         255.255.255.0   U     1024   0        0 
enp2s0.2
192.168.7.0     0.0.0.0         255.255.255.0   U     1024   0        0 
enp2s0.7
[n3150 ~]# traceroute 192.168.7.2
traceroute to 192.168.7.2 (192.168.7.2), 30 hops max, 60 byte packets
 1  192.168.2.1 (192.168.2.1)  0.282 ms  0.298 ms  0.218 ms

[n3150 ~]# 

Why is manjaro trying to route through 192.168.2.1 (i.e. interface enp2s0.2) 
and not enp2s0.7?

On a very similarly configured Debian system on the same network everything 
works as expected:

Any hint or advice is welcome.

Thanks
