debugging ospf route-calc

Function

The debugging ospf route-calc command enables debugging of route calculation of all OSPF processes.

The undo debugging ospf route-calc command disables debugging of route calculation of all OSPF processes.

By default, the debugging of route calculation of all OSPF processes is disabled.

Format

debugging ospf process-id route-calc { all | intra-area | asbr | ase | inter-area | nssa | ti-lfa }

debugging ospf process-id route-calc { intra-area | ase | inter-area | nssa } filter { address-ipv4 mask-length | acl { acl-number | acl-name } }

debugging ospf process-id route-calc asbr filter { address-ipv4 | acl { acl-number | acl-name } }

debugging ospf process-id route-calc ti-lfa filter address-ipv4

undo debugging ospf [ process-id ] route-calc { all | intra-area | asbr | ase | inter-area | nssa | ti-lfa }

undo debugging ospf process-id route-calc { intra-area | ase | inter-area | nssa } filter { address-ipv4 mask-length | acl { acl-number | acl-name } }

undo debugging ospf process-id route-calc asbr filter { address-ipv4 | acl { acl-number | acl-name } }

undo debugging ospf process-id route-calc ti-lfa filter address-ipv4

Parameters

Parameter	Description	Value
process-id	Specifies the ID of an OSPF process.	The value is an integer ranging from 1 to 4294967295.
all	Displays the debugging information about all types of OSPF route calculation.	-
intra-area	Displays debugging information about route calculation of LSAs in the area.	-
asbr	Displays debugging information about route calculation of ASBR LSA.	-
ase	Displays debugging information about route calculation of ASE LSA.	-
inter-area	Displays debugging information about route calculation of LSAs between areas.	-
nssa	Displays debugging information about NSSA route.	-
ti-lfa	Displays debugging information about route calculation of TI-LFA.	-
filter	Indicates the filtering policy.	-
address-ipv4	Indicates Destination of IP address.	The value is in dotted decimal notation.
mask-length	Indicates length of IP address mask.	The value is an integer ranging from 0 to 32.
acl acl-number	Specifies the number of a basic ACL.	The value is an integer ranging from 2000 to 2999.
acl acl-name	Specifies the name of a named basic ACL.	The value is a string of 1 to 64 case-sensitive characters without spaces. The value must start with a letter (a to z or A to Z, case sensitive).
