1 Basic BGP Data Plane Convergence Benchmarking -Rajiv Papneja - Mohan Nanduri -Bhavani Parise - Eric Brendel -Susan Hares - Jay Karthik

2 Background and Current Status Terminology for Benchmarking BGP Device Convergence in the (RFC 4098) / June 2005 Draft focusing on the BGP Data Plane convergence document ready and has been posted on private – Team formed to produce the methodology draft – draft-papneja-bgp-basic-dp-convergence-00.txt – Rajiv Papneja, Bhavani Parise, Susan Hares, 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, failure convergence events Topologies – Several 3 node, and 4 node setups

4 Test Methodologies Considered RIB-IN convergence RIB-OUT convergence iBGP convergence eBGP convergence eBGP multi-hop convergence BGP Failure/Convergence Events – Physical Link failure (local/remote) – ECMP link failure (local/remote) – BGP session failure Hard Reset tests - BGP Non-Recovering Hard Reset BGP Soft Reset BGP Route Withdrawal Convergence measurement BGP Path Attribute Change Convergence Time BGP Graceful Restart Convergence Time

5 Basic test set-up DUTEmulation Routing Interfaces Traffic Interfaces

6 Logical test set-up HLPEmulationDUT AS 1 (IBGP AS 2 (EBGP) AS 1 AS 1 (IBGP AS 3 (EBGP)

7 Logical test set-up HLP EmulationDUT AS 1 (IBGP AS 2 (EBGP) AS 1AS 1 (IBGP AS 3 (EBGP) DUT AS 1 (IBGP AS 4 (EBGP)

8 Goal of work Data + Control plane – Other drafts (Hares*) – Building blocks for AS cp-dp Potential output – Tool kit based on an open source code – Results tested on multiple machines

9 Next Steps Published initial version of the Methodology in July Solicit input from SP community Feedback and comments from the group on the test cases Focus – After review, WG document for standardization
