I created a GNS3 network topology (screenshot provided), but not able to ping R2 (192.168.11.2) from my local machine which is connected to this network via tap1.

The commands I ran are:

#create a tap
sudo tunctl -u <username>
sudo tunctl -t tap1
sudo ifconfig tap1 0.0.0.0 promisc up

#create a dummy interface
sudo modprobe dummy
sudo lsmod | grep dummy
sudo ip link add eth0 type dummy
sudo ip link set eth0 up
sudo ifconfig eth0 0.0.0.0 promisc up

#create & configure the bridge
sudo brctl addbr br1
sudo brctl addif br1 tap1
sudo brctl addif br1 eth0
sudo ifconfig br1 up
sudo ifconfig br1 192.168.211.5/24
sudo brctl show

#create ip routes for the different networks
sudo ip route add 192.168.11.0/24 via 192.168.211.5 dev br1
sudo ip route add 192.168.12.0/24 via 192.168.211.5 dev br1
sudo ip route add 192.168.13.0/24 via 192.168.211.5 dev br1
sudo ip route add 192.168.14.0/24 via 192.168.211.5 dev br1
sudo ip route add 192.168.211.0/24 via 192.168.211.5 dev br1

Am I missing something?
