Motorola 3397GP Set ip dsl vccn mcast-fwd on off, Set ip dsl vccn igmp-null-source-addr on off

Administrator’s Handbook

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-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 dns acquired-dns-priority [ 0 - 255 ]

Sets the priority for DNS acquired via PPP. See “Domain Name System Settings” on page 160 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.

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 support.

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.
