Frame Relay multipoint topology support

The Avaya G450 Media Gateway supports point-to-point frame relay connections. To enable
you to use the G450 as an endpoint in a Point to Multi-Point (PTMP) topology, the G450
supports inverse ARP replies. The G450 responds to inverse ARP queries received on frame
relay sub-interfaces with the proper inverse ARP replies.
When you connect the G450 as an endpoint in a PTMP configuration, you need to increase the
OSPF timers manually. Use the ip ospf network point-to-multipoint command in
Serial interface context to increase the OSPF timers with the following values:
Increase the OSPF Hello Interval to 30 seconds
●
Increase the OSPF Dead Interval to 120 seconds
●
For more information on OSPF, see

Initial WAN configuration

1. Add one of the following WAN media modules:
- Avaya MM340 E1/T1 media module
- Avaya MM342 USP media module
Note:
You can also use a Fast Ethernet port on the G450 chassis as the endpoint for a
Note:
WAN line by configuring this interface for PPPoE. See
