set ip ip-ppp [vcc
n
] auto-sensing [ off | dhcp/pppoe | pppoe/pppoa ]
Enables or disables DHCP/PPPoE or PPPoE/PPPoA autosensing on the specified inter face. 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-
er wise, after attempting to connect via DHCP for 60 seconds, the Gateway switches back to PPPoE.
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 tr ying these protocols in
parallel, and using the first one that is successful.
set ip ip-ppp [vcc
n
] rip-send { off | v1 | v2 | v1-compat | v2-MD5 }
Specifies whether the Motorola Netopia
®
Gateway unit should use Routing Information Protocol (RIP)
broadcasts to adver tise its routing tables to Gateways on the other side of the PPP link. An extension of
the original Routing Information Protocol (RIP-1), RIP Version 2 (RIP-2) expands the amount of useful
information in the packets. While RIP-1 and RIP-2 share the same basic algorithms, RIP-2 suppor ts sev-
eral new features. For example, inclusion of subnet masks in RIP packets and implementation of multi-
casting instead of broadcasting. This last feature 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.
This command is only available when address mapping for the specified vir tual circuit is turned “off”.
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 ip-ppp [vcc
n
] 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 on the other side of
the PPP link.
If you specify
v2-MD5
, you must also specify a
rip-receive-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 ip-ppp vcc
n
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 ip-ppp vcc
n
mcast-fwd [ on | off ]
Specifies whether you want the Motorola Netopia
®
Gateway inter face to act as an IGMP proxy host.
set ip ip-ppp vcc
n
unnumbered [ on | off ]
Specifies whether you want the Motorola Netopia
®
Gateway to have its WAN inter face unnumbered, i.e.
set to 0.
