Frame Relay multipoint topology support

The Avaya G250/G350 Media Gateway supports point-to-point frame relay connections. To
enable you to use the G250/G350 as an endpoint in a Point to Multi-Point (PTMP) topology, the
G250/G350 supports inverse ARP replies. The G250/G350 responds to inverse ARP queries
received on frame relay sub-interfaces with the proper inverse ARP replies.
When you connect the G250/G350 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 Interface Serial 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 the Fast Ethernet port on the G250/G350 chassis as the
Note:
endpoint for a WAN line by configuring this interface for PPPoE. See
