Control Plane – Data PlaneData Plane - Services

• Sends a packet from an input interface to an output interface• 2 basic functions on IPv6

• MAC header swap• IPv6 Hop Limit decrement• No more IP checksum

• Can be done in software or hardware, centralized or distributed

• choices dependent of the platform’s design and market’s target

• IPv6 requires at least a software upgrade and potentially both hardware and software upgrades• IPv6 lookup is deeper than IPv4IPv6 lookup is deeper than IPv4

Cisco IOS IPv6 Data PlaneData Plane• Cisco IOS routers are IPv6-aware through software update.

• only high-end routers may require a hardware upgrade

• CEFv6 is the fast switching path

• 12.2(13)T, 12.2(11)S minimum• dCEFv6 on 7500, 12000 series• On mid-range routers, new generation of processors achieved similar performances as specialized ASIC based routers

• better performances on features such as IPv6 over tunnels, extended ACL

• On Cisco 12000 series, Engine 3 has comparable IPv6 and IPv4 performance

• 4Mpps on IPv4, 3.8Mpps on IPv6 per line card

• 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
