Black Box LRU4240 manual Ospf dead-interval, Ospf hello-interval

Dual Trunk E1 Router

Command Syntax

ospf cost COST

no ospf cost

COST = <1-65535> Specifies the link-state metric.The default value is 10.

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 command to set cost manually.

Examples

ospfd# configure terminal ospfd(config)# interface fxp0 ospfd(config-if)# ospf cost 10

Equivalent Commands

ip ospf cost

ospf dead-interval

Use the ospf dead-interval command to set the interval during which no hello packets are received and after which a neighbor is declared dead.

Use the no form of this command to disable this function

Command Syntax

ospf dead-interval INTERVAL no ospf dead-interval

INTERVAL= <1-65535> Specifies the interval in seconds. The default interval is 40 seconds

Command Mode Interface mode

Usage

The dead-interval is the amount of time that the router waits to receive an OSPF hello packet from the neighbor before declaring the neighbor down. This value is advertised in the router's hello packets. It must be a multiple of hello-interval and be the same for all routers on a specific network.

Examples

ospfd# configure terminal ospfd(config)# interface fxp0 ospfd(config-if)# ospf dead-interval 10 10.10.10.50

Equivalent Commands

ip ospf dead-interval

ospf hello-interval

Use the ospf hello-interval command to specify the interval between hello packets that the ZebOS software sends on the interface.

Use the no form of this command to return to the default setting.

Command Syntax

ospf hello-interval INTERVAL no ospf hello-interval

INTERVAL= <1-65535> Specifies the interval in seconds. The default interval is 10 seconds.

Default

Command Mode

Interface mode

Usage

Hello-interval is advertised in the hello packets. Configure the same hello-interval for all routers on a specific network. A shorter hello interval ensures faster detection of topological changes but this also results in more routing traffic.
