IP routed interface scaling

VSP 4000 supports up to 256 IP-routed interfaces.

When you configure a large number of IP-routed interfaces, use passive interfaces on most of the

configured interfaces. You can make very few interfaces active.

IPv6

IPv6 provides high-performance, scalable Internet communications. Use the information in this

section to help deploy IPv6 in your network. For configuration information, see Configuring IPv6

Routing on VSP Operating System Software, NN47227-507.

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 if you want to segregate all IPv6 traffic into a single VLAN at one switch or

across a set of Layer 2 access switches. The core switch performs hardware-based IPv6 line-rate

routing.

Transition mechanisms

The switch uses the following functions to help you transition your network from IPv4 to IPv6:

• Dual stack mechanism, where the IPv4 and IPv6 protocol stacks can communicate with both

IPv6 and IPv4 devices.

• Tunneling, which involves the encapsulation of IPv6 packets to traverse IPv4 networks, and the

decapsulation of IPv4 packets to traverse IPv6 networks.
