Set ip ip-ppp vccn igmp-null-source-addr on off

Administrator’s Handbook

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 ip-ppp [vccn] rip-send { off v1 v2 v1-compat v2-MD5 }

Speciﬁes whether the Motorola Netopia® Gateway unit should use Routing Information Protocol (RIP) broadcasts to advertise 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 supports 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 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.

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 Gateway(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) 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 support.
