Suppose and are running rip for their intra-as routing protocol

c- to determine good routes from senders to receivers through the network

d- to improve individual router performance metrics

c- The path with the least physical distance between hosts

d- None of the above

c- Each node communicates only with its directly connected neighbors

d- Each node routes packet traffic to each of its neighbor nodes

c- each node sends its routing table directly to its neighbors

d- each node sends information about its links to other nodes via broadcast messages

c- so called "fiefdoms"

d- administrative systems

c- must run OSPF

d- run the same routing protocol

c- backed up

d- invisible

c- intra-AS routing protocol

d- transport layer protocol

c- BGP

d- OSPF

c- RIP

d- OSPF

c- EIGRP

d- the network administrator(s)

c- converting to OSPF

d- CIDRized prefixes (eg 192.168.2.12/22)

c- senders in one AS to reach receivers in a different AS

d- the Internet to function as an integrated whole

17) Routers that connect directly between ASs are called

a- Portal Routers

18) Consider the network shown below. Suppose AS3 and AS2 are running OSPF for their intra-AS routing protocol. Suppose AS1 and AS4 are running RIP for their intra-AS routing protocol. Suppose eBGP and iBGP are used for the inter-AS routing protocol. Initially suppose there is no physical link between AS2 and AS4.

Router 3c learns about prefix (subnet) x from which routing protocol: OSPF, RIP, eBGP, or iBGP?
