  2. View Of Network Topology Control Plane Routing Table Dynamic, Topology-Driven Routing Updates Data Plane Packet Packet L2,3,4 Intelligent Forwarding (CEFv6 Table) Control Plane – Data Plane - Services • Runs on the main processor board • Runs the Routing protocols that computes the network topology • May need large memory size to handle the full Internet routing table • Also use by Network Management • A software upgrade is required to add an IPv6 Control plane

  3. View Of Network Topology Control Plane Routing Table Dynamic, Topology-Driven Routing Updates Data Plane Packet Packet L2,3,4 Intelligent Forwarding (CEFv6 Table) Cisco IOS IPv6 Control Plane • Cisco IOS 12.2T, 12.2S and 12.0S integrate IPv6 • Supported Routing Protocols • Static, RIPng, OSPFv3, IS-IS and MP-BGP • IPv6 Multicast (EFT now) • MLDv1/v2, PIMv2 SM, SSM, IPv6 Multicast address family on MP-BGP, Static Mroute • IPv6 over MPLS, aka 6PE • IPv6 MIBs (new drafts) • IP • IP Forwarding • Ping, Traceroute, Telnet, TFTP, HTTP, DNS client, SSH

  6. View Of Network Topology Control Plane Routing Table Dynamic, Topology-Driven Routing Updates Data Plane Packet Packet L2,3,4 Intelligent Forwarding (CEFv6 Table) Control Plane – Data Plane - Services • Can apply at layer 2, 3, 4 or 7 dependent of the action(s) • Well-known services on a router • Packet filtering, QoS, Encryption, Tunnelling, Translation, Accounting • Can be done in software or get hardware assistance • IPv6 requires a software or both hardware and software upgrades • Parsing an IPv6 header + option header(s) + TCP/UDP port numbers impacts the performances

  7. View Of Network Topology Control Plane Routing Table Dynamic, Topology-Driven Routing Updates Data Plane Packet Packet L2,3,4 Intelligent Forwarding (CEFv6 Table) Cisco IOS IPv6 Services • Key drivers for production deployment and Cisco IOS focus. • A non-exhaustive list • IPv6 QoS • Access Control List • Standard & Extended • Radius AAA IPv6 attributes • All IPv6 Tunnelling mechanisms • 6to4, ISATAP, configured, automatic, GRE • DHCPv6 Prefix Delegation (EFT) • Netflow IPv6 (under development) • NAT-PT

  8. IPv6 in Action

  9. Integration and Transition • Requirements • Enable end-to-end IPv6 transport • Preserve exiting IPv4 infrastructure • Minimize operational upgrade costs • Enabled by • Incremental Upgrade/Deployment of equipment • Use of tunnels, dedicated data links, MPLS (6PE) • No impact on existing cores • Cisco IOS enables IPv6 • Software upgrade path for most platforms • Hardware upgrade for performance • Wide variety of tunnel methods and media
