R
One routing protocol accepts route information from another routing protocol and advertises it in the
redistribution
local autonomous system.
Responsible for guaranteed, ordered delivery of EIGRP packets to all neighbors.
Reliable Transport
Protocol
The dependability (usually described in terms of the bit-error rate) of each network link.
reliability
Routing Information Base. Maintains the routing table with directly connected routes, static routes, and
RIB
routes learned from dynamic unicast routing protocols.
The process that controls route maps and policy-based routing.
Route Policy
Manager
See RIB.
routing information
base
A construct used to map a route or packet based on match criteria and optionally alter the route or
route map
packet based on set criteria. Used in route redistribution and policy-based routing.
A process that replaces a series of related, specific routes in a route table with a more generic route.
route
summarization
A unique identifier used by routing protocols. If not manually configured, the routing protocol selects
router ID
the highest IP address configured on the system.
S
Shortest Path First algorithm. Dijkstra's algorithm used by OSPF to determine the shortest route
SPF algorithm
through a network to a particular destination.
Routes learned from an interface are not advertised back along the interface they were learned on,
split horizon
preventing the router from seeing its own route updates.
Routes learned from an interface are set as unreachable and advertised back along the interface they
split horizon with
were learned on, preventing the router from seeing its own route updates.
poison reverse
A manually configured route.
static route
An OSPF area that does not allow AS External (type 5) LSAs.
stub area
A router that has no direct connection to the main network and which routes to that network using a
stub router
known remote router.
Switched Virtual Interface.
