set ip dsl vccn auto-sensing [ off | dhcp/pppoe | pppoe/pppoa ]
Enables or disables DHCP/PPPoE or PPPoE/PPPoA autosensing on the specified interface. Setting this
to DHCP/PPPoE enables automatic sensing of your WAN connection type: PPPoE or DHCP. The gate-
way attempts to connect using PPPoE first. If the Gateway fails to connect after 60 seconds, it switches
to DHCP. As soon as it can connect via DHCP, the Gateway chooses and sets DHCP as its default. Oth-
erwise, after attempting to connect via DHCP for 60 seconds, the Gateway switches back to PPPoE.
The Gateway will continue to switch back and forth in this manner until it successfully connects. Simi-
larly, selecting PPPoE/PPPoA causes the Gateway to attempt to connect by trying these protocols in
parallel, 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 interface 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 vcc n dns acquired-dns-priority [ 0 - 255 ]
Sets the priority for DNS acquired via PPP. See "Domain Name System Settings" on page 156 for more
information.
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) broad-
casts to advertise its routing tables to other Gateways. RIP Version 2 (RIP-2) is an extension of the orig-
inal 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 algorithms, RIP-2 supports several additional fea-
tures, 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.
