Split Horizon - Only routes not learned on the Ethernet port are advertised.

Poison Reverse (def) - All routes are advertised, including routes learned from the Ethernet port. These routes are poisoned.

None - All routes are advertised, including routes learned from the Ethernet port. No attempt is made to poison these routes.

RIP/Direction

Write security: 3; Read security: 5

Tx and Rx (def)- RIP advertisements are transmitted and listened to on the Ethernet port.

Tx only - RIP advertisements are transmitted and not listened to.

Rx only - RIP advertisements are listened to but not transmitted.

RIP/V2 Secret

Write security: 0; Read security: 0

This is a text string used for authenticating advertised routes.

NAT/DHCP Mode

Write security: 3; Read security: 5

When this option is set to On, the Express XL/XLT acts as a DHCP server and will dynamically assign IP, network mask, default gateway, and DNS ad- dresses to any device which transmits a broadcast DHCP request. The ad- dresses assigned are based on the Express XL/XLT’s own IP address and will be within the same network. This mode is most commonly used with the NAT functionality. The default is Off.
