MSPF.016 IGMP disabled, ifc IP_interface
Long Syntax:

Level:
P-TRACE
Short Syntax:
MSPF.017 Rcvd IGMP Query IP_source -> IP_destination max_rsp= max_response_time grp= multicast_group nt network ID
Long Syntax:
MSPF.017 Received IGMP Host Membership Query, IP_source -> IP_destination max_rsp= max_response_time group= multicast_group net network ID
Description:
An IGMP Host Membership Query has been received. An IGMPv1 Query has max_response_time set to 0; Otherwise, it is an IGMPv2 Query. A general query has the multicast group set to 0.0.0.0; a specific query has the value of the specific multicast group.

U-INFO
Short Syntax:
MSPF.018 Querier= querier_IP_address ifc= IP_interface nt network ID
Long Syntax:
MSPF.018 Querier= querier_IP_address ifc= IP_interface nt network ID
Description:
The querier on the interface has changed. The IP address of the new Querier router is displayed. For IGMPv2, the querier is the router with the lowest IP address. For IGMPv1, the higher level multicast protocol, such as MOSPF, determines the querier.

MSPF.019

Level:
UE-ERROR
Short Syntax:
MSPF.019 Unexpected IGMP Query from IP_source nt network ID
Long Syntax:
MSPF.019 Unexpected IGMP Query from IP_source net network ID
Description:
This router considers itself as the Querier, so receiving a Query from another router is unexpected.
Cause:
A few of these messages coould be normal in the process of determining which router is the Querier. As long as the situation does not persist, there is no problem.
Action:
None
Cause:
The other router is running IGMPv1 and thus does not adhere to the the IGMPv2 querier election rules. Both routers will continue to each be queriers.
Action:
None. Unless there is a problem. It should not hurt, functionally, to have multiple Queriers; there is, of course, a small waste of bandwidth for the each duplicated IGMP message.
Action:
Upgrade the other router to IGMPv2 at your convenience.
Action:
Alternatively, you may also configure this interface to run in IGMPv1 mode.

MSPF.020

Level:
P-TRACE
Short Syntax:
MSPF.020 IGMPv2 LEAVE accept IP_source -> IP_destination grp= multicast_group nt network ID
Long Syntax:
MSPF.020 IGMPv2 LEAVE accepted IP_source -> IP_destination group= multicast_group net network ID
Description:
An IGMPv2 LEAVE for a multicast group has been received on the specified interface and the IGMPv2 LEAVE processing has been initiated.

MSPF.021

Level:
P-TRACE
Short Syntax:
MSPF.021 Rcvd IGMPv1 Report IP_source -> IP_destination grp= multicast_group nt network ID
Long Syntax:
MSPF.021 Received IGMP Host Membership Report IP_source -> IP_destination group= multicast_group net network ID
Description:
An IGMPv1 Host Membership Report for a multicast group has been received on the specified interface.

MSPF.022

Level:
P-TRACE
Short Syntax:
MSPF.022 Rcvd IGMPv2 Report IP_source -> IP_destination grp= multicast_group nt network ID
Long Syntax:
MSPF.022 Received IGMP Host Membership Report IP_source -> IP_destination group= multicast_group net network ID
Description:
An IGMPv2 Host Membership Report for a multicast group has been received on the specified interface.

MSPF.023

Level:
UE-ERROR
Short Syntax:
MSPF.023 Bad IGMP type igmp_pkt_type , src= IP_source nt network ID
Long Syntax:
MSPF.023 Received bad IGMP type igmp_pkt_type , src= IP_source net network ID
Description:
An IGMP message has been received having an unrecognized type field. The message is discarded.
Cause:
The source IP machine is using a newer version of IGMP containing packet types that this router does not support.
Action:
None if there are no problems; otherwise call customer service.

MSPF.024

Level:
UE-ERROR
Short Syntax:
MSPF.024 Unexp IGMPv2 Report IP_source -> IP_destination grp= multicast_group nt network ID
Long Syntax:
MSPF.024 Unexpected IGMPv2 Membership Report IP_source -> IP_destination group= multicast_group net network ID
Description:
An IGMPv2 Host Membership Report for a multicast group has been received on the specified interface, but this router is running IGMPv1. The message is discarded.
Cause:
If this persists, this is an IGMP interoperability problem. An IGMPv2 host is not supposed to send an IGMPv2 report if it is aware that an IGMPv1 router exists. It is supposed to send an IGMPv1 report instead.
Action:
Fix the sending host; it has a IGMP bug.
Action:
Alternatively, reconfigure to run IGMPv2 on this interface, which is the default.

MSPF.025

Level:
P-TRACE
Short Syntax:
MSPF.025 IGMPv2 LEAVE ign rsn= IP_source reaason -> IP_destination grp= multicast_group nt network ID
Long Syntax:
MSPF.025 IGMPv2 LEAVE ignored reason= IP_source reaason -> IP_destination group= multicast_group net network ID
Description:
An IGMPv2 LEAVE for a multicast group has been received, but ingored on the specified interface. The reason why the Leave is ignored is given.
Cause:
The possible reasons are: (1) "in v1 mode", this interface is configured for IGMPv1 mode, (2) "not querier", this interface is not the IGMP querier, (3) "unknown group", the group is not in the router's database, (4) "already leaving", the router is already in the LEAVE processing logic, (5) "cfgd to never process", the interface is hard-configured to not process LEAVEs, (6) "v1 hosts present", there are V1 hosts present in the group.
Action:
None, unless you wanted LEAVE processing.
Action:
If you wanted LEAVE processing, make sure the interface is not configured to never do LEAVE processing. Alos be sure there are no IGMPv1 hosts on the network. If there are V1 hosts and you still want LEAVE processing, configure LEAVE processing to always be on, but this is not normal.

MSPF.026

Level:
P-TRACE
Short Syntax:
MSPF.026 Snt IGMP Query IP_source -> IP_destination max_rsp= max_response_time grp= multicast_group nt network ID
Long Syntax:

Description:
An IGMP Host Membership Query has been sent. An IGMPv1 Query has max_response_time set to 0; Otherwise, it is an IGMPv2 Query. A general query has the multicast group set to 0.0.0.0; a specific query has the value of the specific multicast group.

Short Syntax:
MSPF.027 Add group multicast_group on ifc interface
Long Syntax:
MSPF.027 Add group multicast_group on interface interface
Description:
The router has added a multicast group on the specific interface to its local multicast group database.

Short Syntax:
MSPF.028 Del group multicast_group on ifc interface
Long Syntax:
MSPF.028 Del group multicast_group on interface interface
Description:
