IPv6 Routing Protocols

The JUNOS Internet software implements full IP routing functionality, providing
support for IP version 6 (IPv6). The routing protocols are fully interoperable with
existing IP routing protocols and provide the scale and control necessary for the
Internet core. The software provides support for the following unicast routing
protocols:

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.
BGP—Border Gateway Protocol, version 4, is an EGP that guarantees loop-free
exchange of routing information between routing domains (also called
autonomous systems). BGP, in conjunction with JUNOS routing policy, provides
a system of administrative checks and balances that can be used to implement
peering and transit agreements.
ICMP—Internet Control Message Protocol router discovery is a method that hosts
can use to discover the addresses of operational routers on a subnet.
IS-IS—Intermediate System-to-Intermediate System is a link-state interior gateway
protocol (IGP) for IP networks that uses the shortest-path-first algorithm (SPF
algorithm, also called the Dijkstra algorithm) to determine routes.
OSPF—Open Shortest Path First, version 3 (OSPFv3), supports version 6 of the
Internet Protocol (IPv6). The fundamental mechanisms of OSPF such as flooding,
Designated Router (DR) election, area based topologies and the Shortest Path
First (SPF) calculations remain unchanged. Some differences exist either due to
changes in protocol semantics between IPv4 and IPv6, or to handle the increased
address size of IPv6.
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.
