18.4.2.2.34debug ip ospf spf

Command: debug ip ospf spf no debug ip ospf spf

Function: Enables the OSPF debug function for shortest path algorithm; the “no debug ip ospf spf” command disables this debug function.

Default: Debugging is disabled by default.

Command mode: Admin Mode

18.4.3Typical OSPF Scenario

Scenario 1: OSPF autonomous system.

This scenario takes an OSPF autonomous system consists of five ES4710BD layer 3 switches for example, where layer 3 switch Switch1 and Switch5 make up OSPF area 0, layer 3 switch Switch2 and Switch3 form OSPF area 1 (assume vlan1 interface of layer 3 switch Switch1 belongs to area 0), layer 3 switch Switch4 forms OSPF area2 (assume vlan2 interface of layer 3 Switch5 belongs to area 0). Swtich1 and Switch5 are backbone layer 3 switches, Swtich2 and Switch4 are area edge layer 3 switches, and Switch3 is the in-area layer 3 switch.
