•Enhanced Interior Gateway Routing Protocol (EIGRP)
Enhanced IGRP provides compatibility and seamless interoperation with IGRP routers. An
automaticredistribution mechanism allows IGRP routes to be imported into Enhanced IGRP, and
vice versa, so it is possible to add Enhanced IGRP gradually into an existing IGRP network.
For more infomation on configuring EIGRP, see the chapter `Configuring EIGRP’.
•Open Shortest Path First (OSPF)
Open Shortest Path First (OSPF) is a routing protocol developed for Internet Protocol (IP)
networks by the interior gateway protocol (IGP) working group of the Internet Engineering Task
Force (IETF). OSPF uses a linkstate algorithm in order to build and calculate the shortest path to
all known destinations. Each router in an OSPF area contains an identical link-state database,
which is a list of each of the router usable interfaces and reachable neighbors
For more infomation on configuring OSPF, see the chapter `Configuring OSPF’.
•Routing Information Protocol The Routing Information Protocol (RIP) is a distance-vector protocol
that uses hop count as its metric. RIP is widely used for routing traffic in the global Internet and is
an interior gateway protocol (IGP), which means that it performs routing within a single
autonomous system.
For more infomation on configuring RIP, see the chapter `Configuring RIP’.

Multicast Routing Overview The adaptive security appliance supports both stub multicast routing
and PIM multicast routing. However, you cannot configure both concurrently on a single adaptive
security appliance.
Stub multicast routing provides dynamic host registration and facilitates multicast routing. When
configured for stub multicast routing, the adaptive security appliance acts as an IGMP proxy agent.
Instead of fully participating in multicast routing, the adaptive security appliance forwards IGMP
messages to an upstream multicast router, which sets up delivery of the multicast data. When
configured for stub multicast routing, the adaptive security appliance cannot be configured for PIM.
The adaptive security appliance supports both PIM-SM and bi-directional PIM. PIM-SM is a
multicast routing protocol that uses the underlying unicast routing information base or a separate
multicast-capable routing information base. It builds unidirectional shared trees rooted at a singleRendezvous Point per multicast group and optionally creates shortest-path trees per multicast
source.
Bi-directional PIM is a variant of PIM-SM that builds bi-directional shared trees connecting
multicast sources and receivers. Bi-directional trees are built using a DF election process
operating on each link of the multicast topology. With the assistance of the DF, multicast data is
forwarded from sources to the Rendezvous Point, and therefore along the shared tree to
receivers, without requiring source-specific state. The DF election takes place during Rendezvous
Point discovery and provides a default route to the Rendezvous Point.
