BGP
BGP (Border Gateway Protocol) is the protocol used to exchange routing information between different networks on the internet. It enables autonomous systems (AS)—large networks or groups of networks under a common administration—to communicate and determine the best paths for data to travel.
For customers using CoreSite’s Blended IP service, BGP allows:
- Peering with CoreSite routers for optimized routing
- Advertising customer-owned IP prefixes with proper ASN association
- Receiving full internet routes or default routes based on specific needs
CoreSite supports BGP peering with customers utilizing Blended IP circuits
BGP configuration is free of charge, but must be explicitly requested
Customer must be using a BGP-Capable Layer 3 Device
- Customers may request BGP peering with two CoreSite routers per market via a support request ticket
- Customers wishing to advertise a specific IP prefix must own the prefix and have it properly associated with their Autonomous System Number (ASN)
It is strongly recommended that customers implement RPKI ROA (Resource Public Key Infrastructure Route Origin Authorization)
Invalid RPKI routes will be rejected
Invalid RPKI routes will be rejected
- Customers advertising a leased subnet must provide SWIP (Shared WHOIS Project), LOA, or RPKI documentation from the original prefix owner
- CoreSite can advertise either
- Full Transit Route
- Default route (0.0.0.0/0)
- CoreSite will honor MED (Multi-Exit Discriminator) and Prepends from Customer
