BGP neighbors are routers forming TCP connections for exchanging BGP updates it’s also called BGP peers or BGP speakers.
There are two types of BGP neighbor relationship
- IBGP (internal BGP)
- EBGP (external BGP)
- Internal BGP (iBGP) operates within the same autonomous system.
- External BGP (E BGP) operates in between the multiple autonomous systems
let's see the configuration: -
Topology;-
TASK:
- configure the topology as the diagram, and assign IP addresses to their ports respectively.
- configure IBGP in AS 65110
- configure EBGP between router 2 and router 3
- ensure all the routers get routes from different ASs
