BGP CHAPTER 6:(LAB-CONTINUE)
QUESTION:
15.Configure eBGP peers between NLFAst ISP & Uplink ISP1 , UPlink ISP2 & Cust1 routers.
- For additional practice , you will be configure the NL Fast ISP, Uplink ISP2
and Cust1 routers.
- On Connections where link redundancy is possible , peer using loopback
interface (create static route if required)
- The Cust1 router should advertise its assigned network via BGP.
- Configure authentication between all eBGP peers using a password of your choice.
- Set logical descriptions for each neighbor in the BGP Process.
- Cust1 is private-as.(64512-65535)
