19-20 ip ospf transmit-delay secondsSyntax Description:
Purpose: When an LSA is created, the router sets the LS age field to 0. The transmit delay value is added to the age field of the LSA. This initial value represents the time delay of propagating the LSA over the interface. Initial Cisco IOS Software Release: 10.0 Configuration Example: Modifying the Transmit Delay Value for an OSPF InterfaceConfigure the network in Figure 19-16 and set the transmit delay value on Router A to 2 seconds. Figure 19-16. Transmit Delay Represents the LSA Propagation Delay Over an OSPF Interface
