I am trying to achieve http://www.cisco.com/c/en/us/support/docs/ip/border-gateway-protocol-bgp/13762-40.html#conf3. Only difference from the setting is that the ISP is sending full BGP table instead of the default gateway. I have a problem that r101 won't advertise external routes to r102, which causes problem when r102's upstream peer disconnects and r102 looses all routes.

My configuration:

R101 running config:

router bgp 6001

 bgp router-id 1.1.2.253

Advertisments are not working at all on R101, but I can see advertisments coming from R102. Communication with upstream ISP BGP peers works as expected and I am obtaining full BGP from them.

R101 advertisments

Total number of prefixes 2

Any ideas what might be wrong? Any help appreciated.
