Ip Routing Features And Considerations; Ip Address For The Management Port; Equal Cost Multipath - Avaya 8800 Configuration Manual

Routing fundamentals
If a black hole route is enabled, you cannot add another static route to that destination. You
must delete or disable the black hole route before you add a regular static route to that
destination.

IP routing features and considerations

The Ethernet Routing Switch 8800/8600 has features and capabilities that you can use to
maximize routing efficiency. This section contains information that you can use to help you
configure IP routing.

IP address for the management port
The network management port is assigned a default IP address if the boot.cfg file is not present
when the switch boots. If no configuration file is present when the switch boots, by default the
management port uses the static IP address of 192.168.168.168/24 for the SF/CPU in slot 5
and 192.168.168.169/24 for the SF/CPU in slot 6. If the boot.cfg is present, the management
IP address is obtained from it. At startup, the system searches for the boot.cfg file. If the file is
present, then the system assigns the IP address for the management port.
Equal Cost Multipath
With Equal Cost Multipath (ECMP), the Avaya Ethernet Routing Switch 8800/8600 can
determine up to eight equal-cost paths to the same destination prefix . You can use multiple
paths for load sharing of traffic. These multiple paths allow fast convergence to other active
paths if the network fails. By maximizing load sharing among equal-cost paths, you can use
