- add vlan3 - _ifindex (eth0=0,vlan2=1,vlan3=2)
Now your routing table has entries for both vlan2 and vlan3 with a
metric of 2.
- Support many more device types easily:
- - HSR: ip link add name hsr0 type hsr slave1 dummy3 slave2 dummy4
- VXLAN: ip link add link dummy2 name vxlan199 type vxlan id 199 dev dummy2
group 224.2.0.199 dstport 4789
- IPVLAN: ...
- IFB: ip link add ifb0 type ifb
