•
OSPF—Open Shortest Path First, version 2, is an IGP developed for IP networks
by the Internet Engineering Task Force (IETF). OSPF is a link-state protocol that
makes routing decisions based on the SPF algorithm.
•
RIP—Routing Information Protocol, version 2, is an IGP for IP networks
based on the Bellman-Ford algorithm. RIP is a distance-vector protocol. RIP
dynamically routes packets between a subscriber and a service provider
without the subscriber having to configure BGP or to participate in the service
provider's IGP discovery process.
•
Multicast routing protocols
•
DVMRP—Distance Vector Multicast Routing Protocol is a dense-mode
(flood-and-prune) multicast routing protocol.
•
IGMP—Internet Group Management Protocol, versions 1 and 2, is used to
manage membership in multicast groups.
•
MSDP—Multicast Source Discovery Protocol enables multiple PIM sparse mode
domains to be joined. A rendezvous point (RP) in a PIM sparse mode domain
has a peering relationship with an RP in another domain, thereby discovering
multicast sources from other domains.
•
PIM sparse mode and dense mode—Protocol-Independent Multicast is a
multicast routing protocol used to route traffic to multicast groups that might
span wide-area and interdomain internetworks. In PIM sparse mode, routers
explicitly join and leave multicast groups. PIM dense mode is a flood-and-prune
protocol.
•
SAP/SDP—Session Announcement Protocol and Session Description Protocol
handle conference session announcements.
•
MPLS application protocols
•
LDP—Label Distribution Protocol provides a mechanism for distributing
labels in nontraffic-engineered applications. LDP allows routers to establish
label-switched paths (LSPs) through a network by mapping network-layer
routing information directly to data-link layer switched paths. LSPs created by
LDP can also traverse LSPs created by Resource Reservation Protocol (RSVP).
•
MPLS—Multiprotocol Label Switching enables you to configure LSPs through a
network either manually or dynamically. You can control how traffic traverses
the network by directing it through particular paths, rather than relying on an
IGP's least-cost algorithm to choose a path.
•
RSVP—Resource Reservation Protocol, version 1, provides a mechanism for
engineering network traffic patterns that is independent of the shortest path
determined by a routing protocol. RSVP itself is not a routing protocol, but
is designed to operate with current and future unicast and multicast routing
protocols. JUNOS RSVP software supports dynamic signaling for MPLS LSPs.
