278 Chapter 8. Command Reference
REMOTE SETENCRYPTION (DifÞe-Hellman Encryption)
This command is used to specify encryption based on the Diffie-Hellman key-exchange protocol. Each router
possesses an internal encryption file that is associated with a public key providing 768-bit security. The predefined
keys can be replaced by the user. The configuration file on the router must have a ÒnumÓ suffix (e.g., dh96.num).
REMOTE SETIPOPTIONS
Turns on or turns off the selected IP option for the WAN interface. To select IP options for the Ethernet interface,
use the command eth ip options (page 243).
Several RIP options are available. RIP is a protocol used for exchanging IP routing information among routers.
The RIP options allow you to set IP routing information protocol controls over a point-to-point WAN. For more
information, see IP (RIP) Protocol Controls, on page 81.
option Specify one of the following options:
rxrip Receive and process IP RIP-1 compatible packets and RIP-2 broadcast packets from the remote
site. Also receive and process RIP-2 multicast packets. Set this option if the local router is to
discover route information from other sites connected to the remote router. This is useful for
hierarchical organizations. If you are connecting to another company or an Internet Service
Provider, you may wish to set this option off. The default is off.
rxrip1 Receive and process RIP-1 packets only.
rxrip2 Receive and process RIP-2 packets only.
rxdef Receive default IP route address. When this option is set on, the local router receives the remote
siteÕs default IP route. The default is off.
remoteName Name of the remote router (character string).
Example:
remote setEncryption dese tx 1111111111111111 HQ
remote setEncryption dese rx 2222222222222222 HQ
remote setEncryption DESE_1_KEY|DESE_2_KEY [<filename>] <remoteName>
DESE_1_KEY SpeciÞes that the same key is used in both directions
DESE_2_KEY SpeciÞes that the keys are different
Þlename Name of the Þle containing the DifÞe-Hellman values. If the Þle is not speciÞed, default values
built into the routerÕs kernel are automatically selected.
remoteName Name of the remote router (character string).
Example:
remote setEncryption DESE_1_KEY dh96.num HQ
remote setipoptions <option> on|off <remoteName>
