BGP deploymentRegarding point 1, that heavily depends on what you are =
using for an edge router, more details would be good.

I have some questions regarding, the kind of configuration that is =
typically done, on a BGP-enabled router sitting at the edge of the =
network. My questions may have already been answered earlier, if that's =
the case, then someone please point me to the relevant mails...
1. In general, how many BGP peers should an edge router be capable
of handling, more specifically, how many E-BGP peers
and how many I-BGP peers are typically incident on one edge router.=20
2. In most situations the routes to the stub networks are manually =
injected into BGP.=20
I feel that's the most common scenario but was wondering if running =
some IGP
between the stub network and the provider edge router and then =
importing the routes
from this IGP into BGP is also common ? Is this also done frequently =
enough ?=20
Another option could be to run a BGP session between the stub =
network and
provider edge router. Is this preffered ?=20
Any help/suggestions would be highly appreciated.=20
