[c-nsp] on Bogons and default bgp routes

[Dracul]

Hi list,

i have several BGP networks that only use default routes from a couple of
ISPs. Is it necessary for us to implement bogon lists or just
leave it up to our upstreams? Although we put the basic martian list, we
don't have fullroutes implemented as we only use bgp for redundancy
purposes.

thanks!
