set ip ip-ppp [vccn] peer-address ip_address

Specifies the IP address of the peer on the other end of the PPP link. If you specify an IP address other than 0.0.0.0, your Motorola Netopia® Gateway will not negotiate the remote peer's IP address. If the remote peer does not accept the address in the ip_address argument as its IP address (typically because it has been configured with another IP address), the link will not come up.

The default value for the ip_address argument is 0.0.0.0, which indicates that the virtual PPP interface will accept the IP address returned by the remote peer. If you enter 0.0.0.0, the peer system must be con- figured to supply this address.

set ip ip-ppp [vccn] restrictions { admin-disabled none }

Specifies restrictions on the types of traffic the Motorola Netopia® Gateway accepts over the PPP virtual circuit. The admin-disabledargument means that access to the device via telnet, web, and SNMP is disabled. RIP and ICMP traffic is still accepted. The none argument means that all traffic is accepted.

set ip ip-ppp [vccn] addr-mapping [ on off ]

Specifies whether you want the Motorola Netopia® Gateway to use network address translation (NAT) when communicating with remote routers. Address mapping lets you conceal details of your network from remote routers. It also permits all LAN devices to share a single IP address. By default, address mapping is turned “On”.

set ip ip-ppp [vccn] auto-sensing [ off dhcp/pppoe pppoe/pppoa ]

Enables or disables DHCP/PPPoE or PPPoE/PPPoA autosensing on the specified interface. Setting this to DHCP/PPPoE enables automatic sensing of your WAN connection type: PPPoE or DHCP. The gateway 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. Otherwise, after attempting to connect via DHCP for 60 seconds, the Gateway switches back to PPPoE. The Gateway will continue to switch back and forth in this manner until it successfully connects. Similarly, 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) broad- casts to advertise its routing tables to routers 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 several new features. For example, inclusion of subnet masks in RIP packets and implementation of multicasting instead of broad- casting. 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 router(s) keys for proper operation of MD5 support.
