  1. Basic BGP Data Plane Convergence Benchmarking draft-papneja-bgp-basic-dp-convergence-00 • Rajiv Papneja

  2. Background and Current Status • Terminology for Benchmarking BGP Device Convergence in the (RFC 4098) / June 2005 • Methodology draft focusing on the BGP Data Plane convergence has been posted • http://tools.ietf.org/html/draft-papneja-bgp-basic-dp-convergence-00 • Team • Rajiv Papneja, Susan Hares, Bhavani Parise, Mohan Nanduri, Jay Karthik, & Eric Brendel

  3. Scope of the Draft • BGP Data plane FIB convergence for both IPv4 and IPv6 • Limited to Basic BGP convergence (RFC 4271 functionality with Multi-Protocol BGP (MP-BGP) for IPv6) • BGP Failure/Convergence Events • Considers dependencies on factors impacting convergence: • Number of peers, • Number of routes/peers • Policy Processing/Reconfiguration • Data Traffic characterization – offered load • Various test cases that covers iBGP, eBGP and failure convergence events • Topologies – Several 3 node, and 4 node setups

  4. Test Cases • Basic Convergence Tests • RIB-IN Convergence • RIB-OUT Convergence • eBGP Convergence • iBGP Convergence • eBGP Multihop Convergence • BGP Failure/Convergence Events • Physical Link Failure on DUT End • Physical Link Failure on Remote/Emulator End • ECMP Link Failure on DUT End

  5. Test Cases • BGP Adjacency Failure (Non-Physical Link Failure) on Emulator • BGP Hard Reset Test cases • BGP Non-Recovering Hard Reset Event on DUT • BGP Soft Reset • BGP Route Withdrawal Convergence Time • BGP Path Attribute Change Convergence Time • BGP Graceful Restart Convergence Time 26

  6. Next Steps • Solicit input from the community • Feedback and comments from the group on the test cases • Request to accept the document as WG item
