Entry Description
A Some Cisco Routers may require the definition of a
Router Alert Option to recognize a report from a Client
to join a Multicast group. The IP Router Alert Option is
defined in RFC2113 and was introduced by Cisco.
While this option is not part of the IGMP standard, most
IGMP V2 implementations contain this option.
However, most implementations of IGMP V1 do not
contain this option. This parameter is defined to
prevent possible conflicts in networks in which a Cisco
Router is configured as an IGMP V1 server.
This parameter can assume one of the following (2)
values:
1. YES
2. NO
If set to YES, the CiM will generate IGMP reports to
join Multicast groups as specifically required by some
Cisco Router configurations.
If set to NO, the CiM will generate IGMP reports to join
Multicast groups as defined an implemented by most
IGMP servers.
The Unsolicited Report Interval configures the CiM to
I
generate unsolicited reports to join a Multicast Group at
specified time intervals. Each unsolicited report to join
a Multicast group will use the version of the IGMP
protocol as specified by the IGMP Version used for
Unsolicited Reports option.
The value of the Unsolicited Report Interval specifies
the number of seconds between unsolicited reports. A
value of zero implies that no unsolicited reports to join
a Multicast group should be generated by the CiM.
This option allows a user to save the current
S
configuration of the CiM to permanent storage. This
configuration will be restored on each successive
power cycle of the CiM.
X This option allows a user to exit the current menu and
return to its parent menu.
