Ip Routed Interface Scaling; Internet Protocol Version 6 - Avaya 8800 Planning And Engineering

Layer 3 network design

IP routed interface scaling

The Avaya Ethernet Routing Switch 8800/8600 supports up to 1972 IP routed interfaces using
SF/CPUs that have 256 MB of memory. You can upgrade SF/CPUs that do not have 256 MB by
using the memory upgrade kit (Part # DS1404015). For more information, see Avaya Ethernet
Routing Switch 8800/8600 Upgrades, NN46205-400.
When you configure a large number of IP routed interfaces, use the following guidelines:
• Use passive interfaces on most of the configured interfaces. You can only make very few
interfaces active.
• For Distance Vector Multicast Routing Protocol (DVMRP), you can use up to 80 active
interfaces and up to 1200 passive interfaces. This assumes that no other routing protocols
are running. If you need to run other routing protocols to perform IP routing, you can
enable IP forwarding and use routing policies and default route policies. If you use a
dynamic routing protocol, enable only a few interfaces with OSPF or RIP. One or two
OSPF or RIP interfaces allow the switch to exchange dynamic routes.
• When using Protocol Independent Multicast (PIM), configure a maximum of 10 PIM active
interfaces. The remainder can be passive interfaces. Avaya recommends that you use IP
routing policies with one or two unicast IP active interfaces.

Internet Protocol version 6

Internet Protocol version 6 (IPv6) enables high-performance, scalable internet
communications. This section provides information that you can use to help deploy IPv6 in
your network.
