Configuring IP Multicasting and Multimedia Services

Nortel Networks offers the following multicasting and multimedia services:

• Distance Vector Multicast Routing Protocol (DVMRP) advertises shortest-path routes to

multicasting source networks, that is, any network with hosts that can issue multicast

datagrams.

• Internet Group Management Protocol (IGMP) allows a host to register its local network with

the local router.

• Multicast OSPF (MOSPF) forwards multicast IP traffic within an OSPF Version 2 autonomous

system.

• Protocol Independent Multicast (PIM) routes multicast traffic between members of multicast

groups that are distributed across various regions of the Internet.

• Resource Reservation Protocol (RSVP) allows host systems in an IP network to reserve

resources on RSVP-capable routers for unicast or multicast dataflows.

This manual describes how to configure multicasting and multimedia services on a Nortel

Networks router.

Configuring IP Utilities

The following IP utilities are application protocols that use IP for message transport:

• DNS • FTP

• NetBIOS over IP • TFTP

• NTP • TCP

• Telnet

This manual describes how to configure these IP utilities on a Nortel Networks router and how to

configure global access policies for Telnet, FTP, TFTP, NTP, SNMP, and HTTP Server. This

manual also describes how to configure IP accounting on frame relay interfaces.

Configuring IPv6 Services

Internet Protocol version 6 (IPv6) uses 128 bits for source and destination addresses. The header

also includes a flow control field that an IPv6 host can use to label packets that require special

handling by IPv6 routers, such as packets that require real-time service. This manual describes

how to configure IPv6 and RIPv6 services on a Nortel Networks router.
