Unix virtual interfaces

[Jan Maria Matějka]

Try
# ip link add lo1 type dummy
# ip a add 10.10.10.10/24 dev lo1

The ifconfig tool is deprecated.

Subject: Unix virtual interfaces

Hello,
I'm running bird 2.0.2 on centOS

I've configured 2 virtual interfaces (eth1:1 and lo:1)

When I run show protocol I don't see them. Are virtual interfaces supported
by bird?
I need it in order to advertise by BGP lo:1
