R5 adds two prefixes (21.0.0.0/8 and 22.2.2.0/24) into its BGP table using two network commands. 2. R5 advertises the prefixes to R7, but does not redistribute the routes into its IGP. 3. R7 advertises the prefixes to R6. 4. WebbIf you drop a link, but iBGP stays established due to an alternate path learned via your IGP, then you may not even have to send a single route update to your neighbors - meaning no churn. Minimising the impact of a failure, shortening overall downtime, and reducing churn are the key points to these designs.
