!anycast-routes6 searches for Anycast IP addresses within an IPv6 address block in CIDR notation.
Anycast IP addresses are typically assigned to hosts in distinct physical locations and announced in BGP by multiple Autonomous Systems. The Internet routing infrastructure directs traffic to the "nearest" originating AS, usually determined by the shortest AS-path.
This command accepts an IPv6 CIDR block and returns Anycast routing visibility for that block. In most cases, !anycast-routes can also be used.
