CONFIG Commands
with MD5 authentication is an extension of RIP-2 that increases security by requiring an
authentication key when routes are advertised.
This command is only available when address mapping for the specified virtual 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 router(s) keys for proper operation
of MD5 support.
set ip ip-ppp [ vccn ] rip-receive { off | v1 | v2 | v1-compat | v2-MD5 }
Specifies whether the Motorola Netopia® Gateway should use Routing Information Protocol
(RIP) broadcasts to update its routing tables with information received from other routers
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 router(s) keys for proper oper-
ation of MD5 support.
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 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 ip-ppp vcc n mcast-fwd [ on | off ]
Specifies whether you want the Motorola Netopia® Gateway interface 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 interface
unnumbered, i.e. set to 0.
