LAB: BGP - Filtering with maximum Prefix

-  Configure SW1 so that the peering sessions to R6 is torn down if SW1 learns more than 20 BGP prefixes from either neighbor.
- Once 16 prefixes are received from R6 a warning message should be generated. Once down the peering should attempt to be restarted after three minutes.
- If more than 20 prefixes are learned from R3 on SW1 a warning message should be generated, but the peering session should not be terminated.
