CP Route v1 Vocabulary Ch08

Question 1

Frame Relay Inverse Arp (InARP)

Answer 1

defined in RFC 1293, this protocol enables a Frame Relay-attached device to react to a received LMI “PVC up” message by announcing its Layer 3 address to the device on the end of the PVC

Question 2

Frame Relay mapping

Answer 2

the information that correlates a Frame Replay DLCI to the Layer 3 address of the DTE on the other end of the VC identified by the local DLCI

Question 3

Full mesh

Answer 3

a network design term often used with multiaccess network such as Frame Relay, referring to the case in which a direct communications path exists between every pair of devices in the design

Question 4

Multipoint subinterface

Answer 4

a configuration construct, typically with Frame Relay, in which one logical subinterface can be used to forward traffic to more than one remote router

Question 5

OSPF network type

Answer 5

a characteristic of OSPF interfaces that determines whether a DR election is attempted, whether neighbors must be statically configured, and the default Hello and Dead timer settings

Question 6

Partial mesh

Answer 6

a network topology in which more than 2 devices could physically communicate, but by choice, only a subset of the pairs of devices connected to the network are allowed to communicate directly

Question 7

Virtual Link

Answer 7

with OSPF, the encapsulation of OSPF messages inside IP to a router with which no common subnet is shared for the purpose of either mending partitioned areas or providing a connection from some remote area to the backbone area
