    BOUT UIDE This guide describes Alcatel’s implementation and command usage of BGP4, OSPF, RIP, and multicast routing protocols. It is designed for network managers and administrators who are responsible for the operation of LAN and WAN equipment and are familiar with networks and routing protocols.

  • Page 11: Protocols Overview

    BGP sessions to be fully meshed within an AS. Since the next-hop contains the IP address of a router interface in the next AS, and this IP address is used to perform routing, the interior routing protocol must be able to route to this address. This means that interior routing tables must include entries one hop beyond the AS boundary.

  • Page 13: Rip

    These messages are used by routers to update their routing tables to maintain currency with the state of the network. When a router updates its routing table, it transmits update messages to other routers in the network to enable them to update their routing tables.

  • Page 14: Multicasting

    There are two modes of PIM protocol – Dense mode (DM) and Sparse mode (SM). Alcatel supports SM only in version 8.0 and higher. PIM-DM floods multicast traffic throughout the network initially and then generates prune messages as required.

Source filtering enables a multicast receiver host to signal to a router which groups it wants to receive multicast traffic from, and from which source(s) this traffic is expected. This membership information enables the router to forward traffic only from those sources from which receivers requested the traffic.

    DVMRP router has no active state for a particular source but does have a DVMRP route, it chooses the parent of the DVMRP route as the previous hop. If a PIM-SM router is on the (*,G) tree, it chooses the parent towards the RP as the previous hop. In these cases, no source/group-specific state is available, but the path may still be traced.
