Figure 6: ipv6 ospf debug packet command options for IPv6 network
For
debugging issues related to adjacency formation, the following options can be particularly
useful:
• ip ospf debug packet (on a specific interface) ipv6 ospf debug packet (on a
specific interface)
• debug ospf nfsm debug ipv6 ospf nfsm
• debug ospf ifsm debug ipv6 ospf ifsm
For debugging issues related to OSPF database calculations, SPF, LSA generation and
processing, and related aspects, use the following specific command options:
• debug ospf lsa debug ipv6 ospf lsa
• debug ospf events debug ipv6 ospf events
• debug ospf route debug ipv6 ospf route
The following figure shows the debug ospf lsa command options for an IPv4 network.
