The Gateway will continue to switch back and for th 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 for warding on the specified inter face. If set to
on, this inter face acts as
an IGMP proxy host, and IGMP packets are transmitted and received on this inter face on behalf of
IGMP hosts on the LAN inter face.
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 ever y
IGMP packet transmitted from this inter face 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 adver tised IP address on the
WAN inter face.
set ip dsl vccn unnumbered [ on | off }
Specifies whether you want the Motorola Netopia
®
Gateway to have its WAN inter face unnumbered, i.e.
set to 0.
unnumbered option is only available if the address is set to 0 for the inter face. Enables or
disables unnumbered IP addressing (where an address of 0 is allowed AND the DHCP client is disabled)
on the specified inter face. This setting applies to native IP as well as PPP inter faces to suppor t running
an IPoE inter face 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 160
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 adver tise 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 suppor ts 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 suppor t routing protocols. RIP-2 with
MD5 authentication is an extension of RIP-2 that increases security by requiring an authentication key
when routes are adver tised.
Depending on your network needs, you can configure your Motorola Netopia® Gateway to suppor t RIP-
1, RIP-2, or RIP-2MD5.
If you specify
v2-MD5, you must also specify a rip-send-key. Keys are ASCII strings with a maximum of
31 characters, and must match the other Gateway(s) keys for proper operation of MD5 suppor t.
set ip dsl vccn rip-receive { off | v1 | v2 | v1-compat | v2-MD5 }
Specifies whether the Motorola Netopia® Gateway should use Routing Information Protocol (RIP) broad-
casts to update its routing tables with information received from other Gateways.
