!bgp-cidr6 searches the Internet BGP Routing Information Base (RIB) for an IPv6 address block in CIDR notation.
Border Gateway Protocol (BGP) is the Internet backbone protocol that enables Autonomous Systems to exchange routing and reachability information. IPv6 prefixes announced by ASNs form the global routing table and describe how networks are interconnected.
This command accepts an IPv6 CIDR block and returns its BGP visibility, including originating Autonomous Systems and routing attributes. In most cases, !bgp can also be used for IPv6 prefix lookups.
