ip link add brm type bridge
ip link set eth1 master brm
ip link set veth0 master brm
ip addr add 192.168.23.99/24 dev brm
ip addr add 192.168.23.100/24 dev veth0
ip link set brm up
ip link set veth0 up
sysctl -w net.mpls.conf.veth0.input=1
sysctl -w net.mpls.conf.brm.input=1
ip netns add host1
ip link set veth1 netns host1
ip netns exec host1 ifconfig veth1 192.168.23.200/24 up
