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

2. Configure OSPF on one network.
On S1, insert the IP address, subnet mask, and VLAN ID for the OSPF port. Enable OSPF
on the port. On S2, insert the IP address, subnet mask, and VLAN ID for the OSPF port in
area 1, and enable OSPF on the port. Both routable ports belong to the same network.
Therefore, by default, both ports are in the same area.
3. Configure three OSPF areas for the network.
4. Configure OSPF on two additional ports in a second subnet.
Configure additional ports and verify that IP forwarding is enabled for each switch to ensure
that routing can occur. On S2, insert the IP address, subnet mask, and VLAN ID for the
OSPF port in area 2, and enable OSPF on the port. On S3, insert the IP address, subnet
mask, and VLAN ID for the OSPF port, and enable OSPF on the port.
The three switches exchange Hello packets.
In an environment with a mix of Cisco and Avaya switches/routers, you may need to manually
modify the OSPF parameter RtrDeadInterval to 40 seconds.

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.
