BGP Configuration for Google Global Cache (GGC)
Seems pretty simple till when you get two GGC nodes with copper interfaces.It seems to be pretty simple. Create an eBGP peering with the cache box using the ASN and IPv4/IPv6 space that Google allocates and then advertise all prefixes for customers that are normally advertised on transit peers. This is the way most content caches work.
