debug ospf6

This command debugs the Open Shortest Path First (OSPF) routing protocol for Internet Protocol (IP) Version 6 networks.

Syntax

# debug ospf6

Command

Description

abr

Debugs the OSPF Version 6 Area Border Router (ABR) function. ABRs connect one or more areas to the main backbone network.

asbr

Debugs the OSPF Version 6 ASBR (Autonomous System Boundary Router) function.

border-routers {area-id|router-id}

Debugs the border router (debugs a specific area according to area ID in A.B.C.D. notation, or debugs a specific border router according to that border router's ID in A.B.C.D. notation).

flooding

Debugs the OSPF Version 6 flooding function.

interface

Debugs the OSPF Version 6 interface.

lsa [XXXX/0xXXXX]
{as-external|inter-prefix|inter-router|
intra-prefix|link|
network|router|unknown}

Debugs the OSPF Link State Advertisement.
Debugs according to LS type specified as hexadecimal, or debugs AS-External, Inter-Prefix, Inter-Router, Intra-Prefix, Link, Network, Router or Unknown).
Possible value for each of these:

■

examin (debugs Examining)

■

flooding (debugs Flooding) -or-

■

originate (debugs Originating)

message {all|dbdesc|

hello|lsack|lsreq|

lsupdate|unknown} (recv|send}

Debugs the OSPF Version 6 messages. Debugs:

■

all (All messages)

■

dbdesc (Database Description messages)

■

hello (Hello messages)

■

lsack (Link State Acknowledgement messages)

■

lsreq (Link State Request messages)

■

lsupdate (Link State Update messages)

■

unknown (Unknown messages)

Possible value for each of these:

■

All

■

Received only -or-

■

Sent only

neighbor {event|state}

Debugs the OSPF Version 6 Neighbor. After two routers become OSPF neighbors, they can become adjacent and exchange routing information.

■

event (Debugs OSPF Version 6 neighbor event)

■

state (Debugs OSPF Version 6 neighbor state change)

route {inter-area|intra-area|

memory|table}

Debugs the calculation of the route table:

■

inter-area (Debugs the calculation of the inter-area route)

■

intra-area (Debugs the calculation of the intra-area route)

■

memory (Debugs route memory use)

■

table (Debugs detail)

spf {database|process|time}

Debugs the calculation of the SPF algorithm which computes the best path to all known destinations based on the data in their link state database.

■

database (Log number of Link State Advertisements at the time the SPF is calculated)

■

process (Debugs the detailed SPF process)

■

time (Measures how long it takes to calculate the SPF)

zebra {recv|send}

Debugs Zebra routing software. Zebra provides TCP/IP based routing services with support from routing protocols RIP, OSPF and BGP. Zebra also supports IPv4 and IPv6 routing protocols.

■

Possible values:

■

recv (Debugs only messages received)

■

send (Debugs only messages sent)

Example

This example debugs how long it takes the SPF algorithm to make its calculation:
