IP parameters (default profile) screen
The IP Parameters (Default Profile) screen allows you to configure various IP parameters for IDSL connections
established without an explicitly configured connection profile:
The Netopia R3100 ISDN Router always acts as a DHCP client on the IDSL link when using a Default Profile.
The DHCP server will supply a local IP address and subnet mask. For an IDSL link, Network Address Translation
(NAT) is enabled by default in the Default Profile and the Default Subnet Mask is set to 0.0.0.0. For details on
setting up IP Parameters see “IP Setup and Network Address Translation” on page 11-1.
Routing Information Protocol (RIP) is needed if there are IP routers on other segments of your Ethernet network
that the Netopia R3100 needs to recognize. Set to “Both” (the default) the Netopia R3100 will accept
information from either RIP v1 or v2 routers. Alternatively, select Receive RIP and select v1 or v2 from the
popup menu. With Receive RIP set to “v1,” the Netopia R3100’s Ethernet port will accept routing information
provided by RIP packets from other routers that use the same subnet mask. Set to “v2,” the Netopia R3100
will accept routing information provided by RIP packets from other routers that use different subnet masks.
If you want the Netopia R3100 to advertise its routing table to other routers via RIP, select Transmit RIP and
select v1, v2 (broadcast), or v2 (multicast) from the popup menu. With Transmit RIP v1 selected, the Netopia
R3100 will generate RIP packets only to other RIP v1 routers. With Transmit RIP v2 (broadcast) selected, the
Netopia R3100 will generate RIP packets to all other hosts on the network. With Transmit RIP v2 (multicast)
selected, the Netopia R3100 will generate RIP packets only to other routers capable of recognizing RIP v2
packets.
