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 184.108.40.206.
When I am trying to add route it fails as Network unreachable. ip add default via 220.127.116.11 dev br0
I would need to : ping -I br0 18.104.22.168 ->>>> But fails.
In oracle virtual box VM, these interfaces are configured as internal network ports (inet).
brctl show bridge name bridge id STP enabled interfaces br0 8000.0800275f7d3e no eth0 eth1 ifconfig eth3 eth3 Link encap:Ethernet HWaddr 08:00:27:f9:c1:a8 inet addr:22.214.171.124 Bcast:126.96.36.199 Mask:255.255.255.0 inet6 addr: fe80::a00:27ff:fef9:c1a8/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 ifconfig br0 br0 Link encap:Ethernet HWaddr 08:00:27:5f:7d:3e inet addr:10.1.1.10 Bcast:10.255.255.255 Mask:255.0.0.0 inet6 addr: fe80::a00:27ff:fe5f:7d3e/64 Scope:Link virtualBox:~# ip route add default via 188.8.131.52 dev br0 **RTNETLINK answers: Network is unreachable**** VirtualBox:~# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 br0 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth3 184.108.40.206 0.0.0.0 255.255.255.0 U 0 0 0 eth3 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth2
