I am newbie to networking and trying to ping from bridge interface to another interface configured with different subnet IP address.
I am trying these configuration in oracle virtual BOX VM running with Ubuntu 16.04.
I have three interfaces eth0, eth1, eth3. In which eth0, eth1 are part of bridge br0. The bridge br0 is configured with IP address as 10.1.1.10.
The another interface eth3 is configured as 192.1.168.10.
When I am trying to add route it fails as Network unreachable. ip add default via 192.1.168.10 dev br0
I would need to : ping -I br0 192.1.168.10 ->>>> But fails.
In oracle virtual box VM, these interfaces are configured as internal network ports (inet).
brctl show

ifconfig eth3

When I am trying to ping from bridge interface it is failed. Any ideas how to resolve this issue.
