OSPF configuration task list

To run OSPF, you must first enable OSPF on the router. Make a proper configuration plan to avoid incorrect settings that can result in route blocking and routing loops.

To configure OSPF, perform the following tasks:

Tasks at a glance
(Required.) Enabling OSPF
(Optional.) Configuring OSPF areas: Configuring a stub area Configuring an NSSA area Configuring a virtual link
(Optional.) Configuring OSPF network types: Configuring the broadcast network type for an interface Configuring the NBMA network type for an interface Configuring the P2MP network type for an interface Configuring the P2P network type for an interface
(Optional.) Configuring OSPF route control: Configuring OSPF route summarization Configuring route summarization on an ABR Configuring route summarization on an ASBR Configuring received OSPF route filtering Configuring Type-3 LSA filtering Setting an OSPF cost for an interface Setting the maximum number of ECMP routes Setting OSPF preference Configuring discard routes for summary networks Configuring OSPF route redistribution Redistributing routes from another routing protocol Redistributing a default route Configuring default parameters for redistributed routes Advertising a host route Excluding interfaces in an OSPF area from the base topology
(Optional.) Tuning and optimizing OSPF networks: Setting OSPF timers Setting LSA transmission delay Setting SPF calculation interval Setting the LSA arrival interval Setting the LSA generation interval Disabling interfaces from receiving and sending OSPF packets Configuring stub routers Configuring OSPF authentication Adding the interface MTU into DD packets Setting a DSCP value for OSPF packets Setting the maximum number of external LSAs in LSDB Setting OSPF exit overflow interval Enabling compatibility with RFC 1583 Logging neighbor state changes Configuring OSPF network management Setting the LSU transmit rate Enabling OSPF ISPF Configuring prefix suppression Configuring prefix prioritization Configuring OSPF PIC Setting the number of OSPF logs Filtering outbound LSAs on an interface Filtering LSAs for the specified neighbor Configuring GTSM for OSPF
(Optional.) Configuring OSPF GR Configuring OSPF GR restarter Configuring OSPF GR helper Triggering OSPF GR
(Optional.) Configuring OSPF NSR
(Optional.) Configuring BFD for OSPF
(Optional.) Configuring OSPF FRR
(Optional.) Advertising OSPF link state information to BGP
