Module 8 BGP - absentee-neptune/NET-330 GitHub Wiki
BGP in Packet Tracer
- Means Border Gateway Protocol
- Exchanges routing and reachability information among autonomous systems (AS) on the Internet
- Makes routing decisions based on paths, network policies, or rule-sets
AS Numbers
- A unique ASN is allocated to each AS for use in BGP routing
- AS numbers are important because the ASN uniquely identifies each (aggregated) network on the Internet
Steps to Enable BGP
- Define router instance
>enable
#conf t
#(config)router bgp AS_number_of_router
- Identify peers
#(config-router)neighbor ip_of_peer remote-as AS-number_of_peer
- Advertise Networks
#(config-router)network netowrk_address mask netmask
BGP and OSPF
- When using BGP to distribute OSPF routes, use the following command in BGP configuration:
#(config-router)redistribute ospf instance_number
