ADD IGMPSNOOPING ROUTERADDRESS

Patch Release Note

PCR: 31133

Module: IPG

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

224.0.0.1to 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= {ALLDEFAULTIPMULTICASTROUTERNONE}

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.
