What Do You Understand By Bgp Split-horizon Rule? |
|
Answer» This rule states, “Network prefixes LEARNED from an iBGP peer will not be shared with another iBGP peer” to prevent routing loops. BGP uses the AS_PATH attribute to avoid routing loops, which means a route will not be accepted if the AS_PATH CONTAINS the same AS number of the router where it is receiving. Route-reflector and confederation techniques are used to share iBGP learned networks with another iBGP neighbor.
