Hi this may be easy, i did configure the default gtwy on r7 and I am able to ping it from the cloud. I am not able ping from 192.168.3.0 network to 192.168.2.0 or 192.168.1.0 network , I did put in the network statement and neighbor statement on r7. I also tried ip route it seems not to work .
the interfaces on r7 are .1 and the interfaces on r1 and r2 are .2 .. I would like to to be able to reach .2 from the cloud. can you please help.
You first need to fix your IGP before worrying about BGP. That means from the cloud you need to be able to ping the loopback address of router 1 and router 2. Now, if you are not running any routing protocol then you need static routes from the cloud to both of the r1 and r2 loopback addresses.
Once your IGP if fixed and you can ping from the cloud to r1 and r2 and vice versa, then you can configure your BGP.
