BT Exact successfully completed evaluation of Data Connection Limited's (DCL's) BGP routing software. The DC-BGP software, which forms part of DCL's IP Routing Suite, supports advanced features including virtual routing and BGP/MPLS VPNs (RFC 2547). It also supports non-stop forwarding, distribution of routing tables to multiple locations with distributed processing and no single point of failure, and scaling to many thousands of independent routing tables, as required by Virtual Routers and BGP/MPLS VPNs. DCL's BGP software passed all of the tests and provided all of the functionality required by BT Exact. BT Exact's also report singled out several areas where DCL's BGP implementation scaled beyond current requirements:
- route table capacity in excess of 1.2 million routes.
- a single peer accepting in excess of 1.2 million unique routes
- BGP peer capacity in excess of 996 established BGP peers
- route convergence and route learning times averaging 7 seconds or under for 100,000 routes
DCL's BGP source code can be integrated with the company's MPLS and other IP Routing protocol stacks (including DC-OSPF and DC-ISIS), or can be used on its own, or with third-party products. An optional, highly scalable Routing Table Manager component provides a flexible policy engine to control sharing of routing information with other protocols (typically sharing between an IGP and EGP).
