Troubleshooting IP Routing Protocols (CCIE Professional Development Series)

This section discusses some of the common error messages in OSPF. Some messages are an indication of a bug, but those messages are not discussed in this section. Some messages also are self-explanatory, such as this one:

Warning: Router is currently an ASBR while having only one area which is a stub area

This warning message means that you are trying to redistribute into a stub area.

Here is the list of error messages that will be discussed in this section:

• "Unknown routing protocol"

• "OSPF: Could not allocate router id"

• "%OSPF-4-BADLSATYPE"

• "%OSPF-4-ERRRCV"
