A routing protocol is required that supports: 1)routing update authentication 2)an addressing scheme that conserves IP addresses 3)multiple vendors 4)a network with over 50 routers Which routing protocol fulfills these requirements（）。A、RIPv1B、RIPv2C、EIGR

A.No dynamic interior routing protocol can summarize as shown

B.Unless configured otherwise, EIGRP would automatically summa rize the prefixes as shown in the exhibit

C.With this IP addressing scheme, EIGRP can be manually configured to summarize prefixes at the specified summarization points

D.The IP address design lends itself to OSPF Each summarizing router would be an ABR, summarizing to the next area in the address hierarchy

Intermediate system to intermediate system (IS - IS), is a protocol used by network devices (routers) to determine the best way to forward datagrams through a packet - switched network, a process called routing. Which three attributes are of the IS - IS routing protocol? （）

A. supports VLSM

B. link - state routing protocol

C. operati on is similar to BGP

D. supports two routing levels within an autonomous system

A network administrator is designing a Cisco network for a large company. The network must be able to use minimal bandwidth for routing updates, converge quickly, and support VLSM, CIDR, IP and IPX. Which routing protocol will best fit the requirements of this network?（）

A. RIP v1

B. RIP v2

C. IGRP

D. OSPF

E. EIGRP

You need to implement the use of a routing protocol that meets the followingrequirements:1. Converges quickly2. Supports VLSM, CIDR, IP, and IPX.3. Uses minimal bandwidth for routing updates.Which one of the following routing protocols would be the best choice?（）

A. RIPv1

B. RIPv2

C. IGRP

D. OSPF

E. EIGRP

A. If using IS-IS as the PE-CE routing protocol, no redistribution is required.

B. If using static routes between the CE and PE routers, no redistribution of other VPN routes is required.

C. If the PE-CE protocol is not BGP, redistribution of other VPN routes from MP-BGP is required.

D. If RIP is the routing protocol that is used between the PE-CE routers, no redistribution is required, but any other protocol will require redistribution.

E. If using OSPF or EIGRP as the PE-CE routing protocol, redistribution is not required, but any other protocol or static route will require redistribution.

A.EIGRP converges fast RIP because of DUAL and backup routes that are stored in the topology table.

B.EIGRP uses a hello protocol to establish neighbor relationships

C.EIGRP uses split horizon and reverse poisoning to avoid routing loops.

D.EIGRP uses periodic updates to exchange routing information

E.EIGRP allows routers of different manufacturers to interoperate

F.EIGRP supports VLSM and authentication for routing updates.

G. EIGRP use a broadcast address to send routing information.

A.If RIPv2 is the routing protocol, only the path AD will be installed in the routing table by default.

B.If RIPv2 is the routing protocol, the equal cost paths ABD and ACD will be installed in the routing table by default.

C.If EIGRP is the routing protocol, only the path AD will be installed in the routing table by default.

D.If EIGRP is the routing protocol, the equal cost paths ABD and ACD will be installed in the routing table by default.

E.If EIGRP and OSPF are both running on the network, the EIGRP paths will be installed in the routing table.

F.If EIGRP and OSPF are both running on the network, the OSPF paths will be installed in the routing table.
