Motorola 7.7.4 Set ip dsl vccn mcast-fwd on off, Set ip dsl vccn igmp-null-source-addr on off

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-fwdis 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.
