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.
Examples
ip ospf authentication-key 123
Equivalent Commands
ospf authentication-key, area authentication
ip ospf cost
Use the ip ospf cost command to explicitly specify the cost of sending a packet on an interface.
Use the no form of this command to reset the path cost to the default value.
Command Syntax
ip ospf cost COST (A.B.C.D)
no ip ospf cost (A.B.C.D)
COST = <1-65535> Specifies the link-state metric.The default value is 10.
A.B.C.D = IP address of the interface
Command Mode
Interface mode
Usage
The interface cost indicates the overhead required to send packets across a certain interface. It is inversely proportional to the
bandwidth of that interface. By default, the cost of an interface is calculated based on the bandwidth (108/ bandwidth);
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
ospfd(config)# interface fxp0
ospfd(config-if)# ip ospf cost 10 10.10.10.50ip ospf cost 123

ip ospf database-filter
This command turns on the LSA database-filter for a particular interface. Use the no parameter to turn off the filter.
Command Syntax
ip ospf database-filter ALL OUT (A.B.C.D)
no ip ospf database-filter (A.B.C.D)
ALL = Filter all LSAs
OUT = Outgoing LSAs
A.B.C.D = IP address of the interface.
Default
Disabled, all outgoing LSAs are flooded to the interface.
