·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 distancevector 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 single Rendezvous 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.
