4 ADD IGMPSNOOPING ROUTERADDRESS Patch Release Note
Patch 86261-04 for Software Release 2.6.1
C613-10386-00 REV D
This PCR introduces an enhancement that extends an issue that was
resolved in PCR 03890, in which switch port entries are only created for
special router multicast addresses. It is now possible to specify reserved
multicast addresses that will be treated as multicast packets from routers.
Use the following commands to configure this feature.
ADD IGMPSNOOPING ROUTERADDRESS
Syntax ADD IGMPSNOOPING ROUTERADDRESS=ipaddr[,...]
Description where:
• ipaddr is a reserved IP multicast address in dotted decimal notation.
This command adds reserved IP multicast addresses to the list of router
multicast addresses. The IP address specified must be within the range
224.0.0.1 to 224.0.0.255. This command is only valid if the IGMP snooping
router mode is set to IP with the SET IGMPSNOOPING ROUTERMODE
command.
SET IGMPSNOOPING ROUTERMODE
Syntax SET IGMPSNOOPING ROUTERMODE=
{ALL|DEFAULT|IP|MULTICASTROUTER|NONE}
Description This command sets the mode of operation for IGMP Snooping.
If ALL is specified, all reserved multicast addresses (i.e. 2240.0.1 to
224.0.0.255) are treated as router multicast addresses.
If DEFAULT is specified, the following addresses are treated as router
multicast addresses:
• IGMP Query: 224.0.0.1
• All routers on this subnet: 224.0.0.2
• DVMRP Routers: 224.0.0.4
• OSPFIGP all routers: 224.0.0.5
• OSPFIGP designated routers: 224.0.0.6
• RIP2 routers: 224.0.0.9
• All PIM routers: 224.0.0.13
• All CBT routers: 224.0.0.15
If IP is specified, addresses that are treated as router multicast addresses are
specified with the ADD/DELETE IGMPSNOOPING ROUTERADDRESS
command. In this mode, the switch will retain previous addresses that have
already been specified.
If MULTICAST is specified, the following addresses are treated as router
multicast addresses:
• DVMRP Routers: 224.0.0.4
• All PIM routers: 224.0.0.13
If NONE is specified, no router ports are created.
