Dual Trunk E1 Router

Authentication password not specified.

Command Mode

Interface mode

Usage

This command creates a password (key) that is inserted into the OSPF header when ZebOS software originates routing protocol packets. Assign a separate password to each network for different interfaces. All neighboring routers on the same network with the same password exchange OSPF routing data.

The key can be used only when authentication is enabled for an area. Use the area authentication command to enable authentication.

Simple password authentication allows a password to be configured for each area. Configure the routers in the same routing domain with the same password.

use this ip ospf cost command to set the cost manually.

Examples

The following example shows setting ospf cost as 10 on interface fxp0 for IP address 10.10.10.50 ospfd# configure terminal
