Disabling and Reenabling Incremental SPF
By default, when changes occur to a type 5 or type 7 LSA, OSPF recalculates new,
loop-free routes for only the LSAs that change. When a subset of LSAs in the external
link-state database change, a full recalculation is not necessary. However, through
the CLI, you can disable incremental SPF so the router can perform a full SPF on all
external LSAs in the link-state database.
disable-incremental-external-spf
■
Use to disable incremental external SPF on the router. When issued, this
command results in a full SPF when an event occurs to trigger an external SPF.
■
Example
host1(config-router)# disable-incremental-external-spf
■
Use the no version to reenable incremental SPF on this router.

Configuring OSPF Traps
You can use the traps command to specify OSPF traps. This command enables you
to specify all or any number of the following trap settings:
■
virtIfStateChange—To indicate any state change on an OSPF virtual interface
■
nbrStateChange—To indicate any state change on a nonvirtual OSPF neighbor
■
virtNbrStateChange—To indicate any state change on a virtual OSPF neighbor
■
ifConfigErro—To indicate any configuration mismatch with a nonvirtual neighbor
■
virtIfConfigError—To indicate any configuration mismatch with a virtual neighbor
■
ifAuthFailure—To indicate any authentication failure on a nonvirtual interface
■
virtIfAuthFailure—To indicate any authentication failure on a virtual interface
■
ifRxBadPkt—To indicate the receipt of a packet that the router cannot parse
■
virtIfRxBadPkt—To indicate the receipt of a packet on a virtual interface that the
router cannot parse
■
txRetransmit—To indicate the retransmittal of a packet on a nonvirtual interface
■
virtTxRetransmit—To indicate the retransmittal of a packet on a virtual interface
■
originateLsa—To indicate the origination of a new LSA by this router
■
maxAgeLsa—To indicate that an LSA in this router LSDB has reached its
maximum age value
■
ifStateChange—To indicate a state change on an OSPF interface
