4.5.1

Example: Without Physical Separation

In a configuration with the cluster of two interconnected L-2 switches, the Avaya G860
Media Gateway's uplink is connected directly to L-2 switches. The two Ethernet Switch
boards must not be interconnected externally as this, combined with the inter-
communication between the L-2 switches, causes a closed loop in the network.
Active Ethernet Switch
Note:
This configuration is more economical when more than one Avaya G860 Media
Gateway is deployed at a single site. The local communication between multiple
Avaya G860 Media Gateways passes through the two interconnected L-2 switches
while all external communication passes through ports to the external router. The
cables to the external router must meet the requirements of external communication.
4.5.2

Example: With Physical Separation

In a configuration with physical separation, the Avaya G860 Media Gateway connects
up to three networks. Each Ethernet Switch (ES) connects to the L2 Switches of each
of the three networks. The duplicate ES connections provide High-Availability.

For ES/6600, the interconnection between the Avaya G860 Media Gateway
and external equipment can be aggregated for media traffic to achieve a
maximum 3 Gigabit Ethernet bandwidth.
For multiple networks, apply these methods to each of the networks in the
network configuration.
