  1. Softwire Mesh MIBdraft-cui-softwire-mesh-mib-04 Peng Wu, Tsinghua Univ. IETF 83, Paris

  2. Background • The WG publishes RFC5565 for Softwire Mesh • CNGI deployment in China • China’s Next Generation Internet • 4-over-6 mesh in CERNET2 • 100 PE routers support softwire mesh AFBR functions • Vendor support on AFBR • Management requirements • Status monitoring, traffic statistics, tunnel management, etc. • Softwire Mesh MIB for RFC5565

  3. Relationship with Other MIBs • Leverage IP Tunnel MIB(RFC4087) • IP Tunnel MIB includes common tunnel objects • Further objects required by Softwire Mesh • Supported tunnel types of the AFBR • Encapsulation table • Leverage BGP MIB(RFC4273) • Softwire Mesh leverages extended MP-BGP • BGP MIB is adopted as well • Further objects required by Softwire Mesh • List of BGP neighbors which runs Softwire Mesh • Encapsulation method negotiated with these neighbors

  4. Softwire mesh MIB structure • swmMIB ::= {transmission xxx} • swmTunnelTypeTable ::= {swmMIB 1} • swmEncapTable ::= {swmMIB 2} • swmBGPNeighborInfo ::= {swmMIB 3} • swmMIBConformance ::= {swmMIB 4}

  5. swmTunnelTypeTable::= {swmMIB 1} • Softwire Mesh Tunnel Type Table • Encapsulation methods which An AFBR supports • Indexed by ifIndex & swmTunnelType • RFC5565 encapsulation method set: {IP-IP, GRE, L2TPv3 (RFC5512), IPsec(RFC5566)}

  6. swmEncapTable::= {swmMIB 2} • Softwire Mesh Encapsulation Table • Encapsulation rule: (E-IP prefix, I-IP dstaddr) binding • Cover both IPv4-over-IPv6 and IPv6-over-IPv4 • Indexed by ifIndex & swmEncapsEIPDst & swmEncapsEIPMask An IPv4-over-IPv6 example

  7. swmBGPNeighborInfo::= {swmMIB 3} • Softwire Mesh BGP Neighbor Information • Neighbor I-IP address • Encapsulation method(s) negotiated between AFBR and the neighbor • Indexed by ifIndex & swmBGPNeighborAddress 4over6 BGP neighbor info example

  8. Next step • This document is in the Softwire Milestone • Nov 2011 Adopt Mesh topology MIB module document as a Working Group document • Nov 2012 Submit Mesh topology MIB module document for Proposed Standard • We’ve addressed the issues raised in past meetings and mailing list • The MIB structure & content are quite clear now • So, request for WG adoption?

  9. Backup slidesManagement requirements • Technical requirements • Monitor the status of PEs’ mesh functions • When broken, analyze information like BGP connectivity, NLRI-NH to find what & where is the problem • Collect each PE’s traffic information, find the bottleneck, etc. • Manage a large number of PEs • Produced by different vendors • Managed by different campus networks • Unified management is indeed necessary
