1214 CHAPTER 72: IPV6 MULTICAST ROUTING AND FORWARDING CONFIGURATIONexceed the maximum number allowed by the system. This maximum value varieswith different device models.If the configured maximum number of downstream nodes (namely the maximumnumber of outgoing interfaces) for a routing entry in the IPv6 multicast forwardingtable is smaller than the current number, the downstream nodes in excess of theconfigured limit will not be deleted immediately; instead they must be deleted bythe IPv6 multicast routing protocol. In addition, newly added downstream nodescannot be installed to the routing entry in the forwarding table.If the configured maximum number of routing entries in the IPv6 multicastforwarding table is smaller than the current number, the routes in excess of theconfigured limit will not be deleted immediately; instead they must be deleted bythe IPv6 multicast routing protocol. In addition, newly added routing entriescannot be installed to the forwarding table.Follow these steps to configure the IPv6 multicast forwarding table size:Displaying andMaintaining IPv6Multicast Routing andForwardingTo do...
