[c-nsp] Redistributed connected / static prefixes to upstream and set as-path prepend

[Florin Florian]

Hi,

You have to use the "ip bgp-community new-format" in order to see the
community in the format.

You should try to configure "neighbor x.x.x.x send-community" for the
community to be sent to the peer (upstream provider in this case).

Setting it in the route-map alone will not do it.

Regards
