What I configured wrong on 7206?
BGP is up on 7206 and I can ping any host outside my network from this router. But routing does not work on it. I can't to ping any host from my network to outside.

You have flip-flopped primary and secondary IP addresses on g0/1.195 (old vlan 195). This may be part of you problem. Can you post 'sh ip bgp s'?

It flip-flopped primary and secondary IP addresses on g0/1.195 and vlan 195 is a result of my experiments on config.

It was my error.
In config 7206 bgp
no auto-summary was wrong line.
Now it works fine with
auto-summary
