Lee be careful about your NDA.
Pls re-read the DOC CD for the ignore MOSPF command.
CIsco routers do not support that LSA so there is no problem of filtering or
ignoring those LSA's.
Thats the only command available to avoid generating many syslog messages
when these LSA's are received.
HTH,
------------------------
ignore lsa mospf
To suppress the sending of syslog messages when the router receives
link-state advertisement (LSA) Type 6 Multicast OSPF (MOSPF) packets, which
are unsupported, use the ignore lsa mospf command in router configuration
mode. To restore the sending of syslog messages, use the no form of this
command.
ignore lsa mospf
no ignore lsa mospf
Syntax Description
This command has no arguments or keywords.
Defaults
This command is disabled by default. Each MOSPF packet causes the router to
send a syslog message.
Command Modes
Router configuration
Command History
Release Modification
11.1
This command was introduced.
Usage Guidelines
Cisco routers do not support LSA Type 6 MOSPF packets, and they generate
syslog messages if they receive such packets. If the router is receiving
many MOSPF packets, you might want to configure the router to ignore the
packets and thus prevent a large number of syslog messages.
