IPv6 requirements
To use IPv6, the switch requires at least one 8895 SF/CPU or 8692 SF/CPU module with Enterprise
Enhanced CPU daughter card (SuperMezz)
IPv6 design recommendations
Avaya Layer 2 and Layer 3 Ethernet switches support protocol-based IPv6 VLANs. To simplify
network configuration with IPv6, Avaya recommends that you use protocol-based IPv6 VLANs from
Edge Layer 2 switches. The core switch performs hardware-based IPv6 line-rate routing.

Transition mechanisms for IPv6
The Avaya Ethernet Routing Switch 8800/8600 helps networks transition from IPv4 to IPv6 by using
three primary mechanisms:
• Dual Stack mechanism, where the IPv4 and IPv6 stacks can communicate with both IPv6 and
IPv4 devices
• Tunneling, which involves the encapsulation of IPv6 packets to traverse IPv4 networks and the
encapsulation of IPv4 packets to traverse IPv6 networks
• Translation mechanisms, which translate one protocol to the other
Dual-stack tunnels
A manually configured tunnel (as per RFC 2893) is equivalent to a permanent link between two IPv6
domains over an IPv4 backbone. Use tunnels to provide stable, secure communication between two
edge routers or between an end system and an edge router, or to provide a connection to remote
IPv6 networks.
