CONFIG Commands
PPPoE/PPPoA causes the Gateway to attempt to connect by trying these protocols in par-
allel, and using the first one that is successful.
set ip dsl vccn mcast-fwd [ on | off }
Enables or disables multi-cast forwarding on the specified interface. If set to on, this inter-
face acts as an IGMP proxy host, and IGMP packets are transmitted and received on this
interface on behalf of IGMP hosts on the LAN interface.
set ip dsl vccn igmp-null-source-addr { on | off }
Specifies whether you want the Motorola Netopia® Gateway to identify the source IP
address of every IGMP packet transmitted from this interface as 0.0.0.0 when mcast-fwd
is set to on. This complies with the requirements of TR-101, and removes the need for a
publicly advertised IP address on the WAN interface.
set ip dsl vccn unnumbered [ on | off }
Specifies whether you want the Motorola Netopia® Gateway to have its WAN interface
unnumbered, i.e. set to 0. unnumbered option is only available if the address is set to 0
for the interface. Enables or disables unnumbered IP addressing (where an address of 0 is
allowed AND the DHCP client is disabled) on the specified interface. This setting applies to
native IP as well as PPP interfaces to support running an IPoE interface without an
address.
set ip dsl vccn rip-send { off | v1 | v2 | v1-compat | v2-MD5 }
Specifies whether the Motorola Netopia® Gateway should use Routing Information Protocol
(RIP) broadcasts to advertise its routing tables to other routers. RIP Version 2 (RIP-2) is an
extension of the original Routing Information Protocol (RIP-1) that expands the amount of
useful information in the RIP packets. While RIP-1 and RIP-2 share the same basic algo-
rithms, RIP-2 supports several additional features, including inclusion of subnet masks in
RIP packets and implementation of multicasting instead of broadcasting (which reduces
the load on hosts which do not support routing protocols. RIP-2 with MD5 authentication is
an extension of RIP-2 that increases security by requiring an authentication key when
routes are advertised.
Depending on your network needs, you can configure your Motorola Netopia® Gateway to
support RIP-1, RIP-2, or RIP-2MD5.
