Adding a BGP Customer
sh conf produces too many lines, can you just
give me a little example?
Procedure
- Test the link with a ping.
- Obtain list of prefixes from customer.
- Verify using whois x.x.x.x@whois.arin.net that customer has been
assigned the prefix.
- Create prefix-list filter.
- Setup BGP session.
- Verify routes received and routes announced.

MULTIHOP
Multihop where the customer is on the other side of a nonbgp speaking edge
router in our network. We peer with their interface address. We add a
static route to their address space on our edge router. They peer with our
loopback address. They add a static route to our loopback address
pointing at our edge routers interface address.
