[c-nsp] BGP Question

[Tantsura, Jeff]

Mark,

It's quite normal to originate routes somewhere in your network and then
advertise these via IBGP to borders. Aggregation is usually configured on
borders.

Hi ,

 

Another BGP question.

 

If we peer with an upstream provider 'piggybacking' on their AS due to
legacy issues, can we announce a new portion of address space via the
network statement on our iBGP peers. Will this get announced the the
Net, or does also need done at eBGP peers i.e our upstreams edge
routers?

 

I suppose what I'm asking here is does information from iBGP routers get
propogated to eBGP routers and onward.

 

The more I think I understand BGP, the more I don't.

 

Thanks,

Mark.
