10 - Advanced Routing Concepts Flashcards
What are the three common characteristics of dynamic routes?
IGP or EGP
classful or classless routing updates
distance-vector or link state routing protocols
What is the collection of all networks managed by a single organization?
Autonomous System
What are IGPs?
routing protocols that dynamically share routing information within an AS
What are EGPs?
routing protocols that dynamically share routing information between multiple ASs
What are the common IGPs in todays networks?
RIP
EIGRP
OSPF
What are the common EGPs in today network?
BGP
What do classful routing protocols do?
- transmit network addresses but not subnet masks
2. automatically summarize networks on their classful bit boundaries
What do classless routing protocols do?
- transmit network addresses and subnet masks
2. enables the use of VLSMs
What happens when ip classless is disabled on a router?
Disables the support of vlsm on classless routing protocols
Is ip classless enabled by default?
yes
What is an example of distance-vector routing protocol?
RIP
What is an example of link-state routing protocol?
OSPF
What is an example of a hybrid routing protocol?
EIGRP
Routers that run distant-vector routing protocol exchange routing updates with ______________?
directly connected neighbors
Routers that use link-state routing protocol flood the network with ___________ packets every time a topology change occurs?
LSA or link state advertisements
