Re: specific route update to bgp with community

ok. GD is Anomaly Guard Module , This module is seated in C6509 MSFC, When Attack Start , GD will float static route to MSFC and then MSFC BGP announce to Peer device,

R3 Running IBGP, IGP, and RX is External Router to redirect traffic when attack from ISP1, RED link is BGP announce Route( Guard floating static route = zone )
