Tasks used to configure basic IP multicast.Īll the packets with reserved link-local addresses are punted to CPU by default in the Cisco ASR 903 RSP2 Module. Applications that take advantage of multicast include video conferencing,Ĭorporate communications, distance learning, and distribution of software, stock quotes, and news. To potentially thousands of corporate businesses and homes. IP multicast is a bandwidth-conserving technology that reduces traffic by delivering a single stream of information simultaneously
