SMCD3GNV4 and SMCD3GNV4E Wireless EMTA Gateway Administrator Manual 

Interface Name 

Select the Gateway interface on which routing is to be performed. 

RIP Send Version 

Select the format and the broadcasting method of the RIP packets that the Gateway sends. Choices 

are: 

• 

RIP1 

• 

RIP2 

• 

RIP1/2 

Your selection should match the version supported by other routers on your network. 

RIP Receive Version 

Select the format and the broadcasting method of the RIP packets that the Gateway receives. Choices 

are: 

• 

RIP1 

• 

RIP2 

• 

RIP1/2 

Your selection should match the version supported by other routers on your network. 

Update Interval 

Specify how often, in seconds, the Gateway sends routing-update messages. 

Default Metric 

Enter a number by which the metric value for the path increases when the Gateway receives a routing 

update that includes changes to an entry. Choices are 1 – 15. Default is 1. 

Authentication Type 

Select the authentication mechanism used, if any. Choices are: 

• 

No Authentication = no authentication is used. If you keep this default setting, the Authentication 

Key & ID fields are gray and unavailable. 

• 

Simple Password = an authentication method where a clear text password is sent to participating 

neighbors on the network. This selection sends the authenticating password over the network, 

possible making it available to individuals who can access packets off the network. Do not use this 

option as part of your security strategy, Rather, use it to avoid accidental changes to the routing 

infrastructure. If you select this setting, the first field in the Authentication Key & ID option becomes 

available for entering the password. 

• 

md5 = an authentication method that works much like Simple Password authentication, except that 

MD5 does not send the key over the network. Instead, a router uses the MD5 algorithm to produce 

a message digest of the key (also called a hash). The router sends the message digest instead of 

the key itself, which ensures that no one can eavesdrop on the network and learn keys during 

transmission. If you select this setting, the first field in the Authentication Key & ID option becomes 

available for entering the key and the second field becomes available for entering the ID. 

Authentication Key & ID 

Specify the appropriate information based on the Authentication Type selected: 

• 

No Authentication = no entry required. 

• 

Simple Password = in the first field, enter the clear-text password to be used for authentication. 

The second field requires no entry, and is gray and unavailable. 

• 

md5 = in the first field, enter the MD5-hash password. In the second field, enter the Key Identifier 

that identifies the key used to create the authentication data for this message. 

Neighbor IP 

Enter the IP address of the Gateway’s RIP neighbor router.
