ccnp三门考试是最简单的考试吧,实验配置很简单。我考完了三门,np收官,但是感觉自己还只是理论上的np,但是要说到实践,思科核心设备都没见过,惭愧了,打算开始朝最顶级的ccie发展吧,以后有什么资料,我会在论坛里无私地发给大家。
下面,是我的路由考试的实验总结 , 还有一些网友挖出来的题目。ccnp三门考试我都发了总结的帖子,准备考试的可以都看看。
实验总结:
一.OSPF Sim 此题要注意的是network后面的是网络号(192.1684.4 0.0.0.3),
需要我们推测,记录,
然后后面要 加area 1
ABR上要
area1 no-summary
Portland:
en
sh running-config 看看是否是 ospf 1
cisco
conf t
router ospf 1
network 192.168.4.4 0.0.0.3 area 1
area 1 stub
end
copy running-config startup-config
Amani:
en
cisco
sh running-config 看看是否是 ospf 1
conf t
router ospf 1
network 192.168.4.4 0.0.0.3 area 1
area 1 stub no-summary ----因为Amani是ABR所以要打上no-sunmmary
end
copy running-config startup-config
二.IPv6 OSPF Virtual Link Sim
解题思路:由于R1/R2/R3/R4建立的虚链路都是错的,所以,首先将全部路由器上的虚链路都NO掉。
R1/R2/R3/R4
sh running-config 看下OSPF进程号不一定是1,而且no掉一些部分。做记录
no area xx virtual-link x.x.x.x
然后,因为是在R2和R3上做虚链路
R2:
en
sh run
conf t
ipv6 router ospf 1 看下OSPF 进程号 不一定是1
area 11 v 3.3.3.3
end
copy running-config startup-config
R3:
en
sh run
conf t
ipv6 router ospf 1 看下OSPF 进程号 不一定是1
no area 54 v 4.4.4.4
area 11 v 2.2.2.2
end
copy running-config startup-config
R4: 这是不用配置虚拟链路的!!!不要画蛇添足!
en
sh run
conf t
ipv6 router ospf 1
no area 54 v 3.3.3.3
end
copy running-config startup-config
R1上show ipv6 route 看是否有R4的环回地址
三.EIGRP Stub Sim
解题思路:先在R3上sh running-config 看下EIGRP进程号和错误之处“eigrp stub receive-only”
R3:
en
sh run
conf t
router eigrp 123
no eigrp stub receive-only
eigrp stub -----这个是题目要求用的命令
end
copy running-config startup-config
show ip route 根据题意配置10.0.0.0的两个子网
R4:
en
show running—config 看eigrp的进程号
conf t
int s0/0 (看端口号是否是s0/0)
ip summary-address eigrp 123 10.0.0.0 255.0.0.0
end
copy running-config startup-config
R4去ping下R3,然后在R3上show ip route 看是否只有两个
四.Policy BasedRoutim
解题思路:此题想用BGP来做,但题库好像提示不能做
CoreRouter:
en
conf t
access-list 101 permit tcp any any eq www
route-map pbr permit 10
match ip address 101
set ip next-hop 10.1.101.1
exit
route-map pbr permit 20
exit
int f0/0
ip policy route-map pbr 这句要记得配啊!
end
copy running-config startup-config
在路由上show route-map 或者在host上点,再点generate,看是否有9 packets
五.EIGRP和OSPF重分发
提示:先在R2上show int s0/0/0 R3上show int f0/0 查看K值,延迟要除以10
在两个路由器show running-config 看ospf的进程号
R2:
en
show int s0/0/0 ------查看BW Delay MTUd等
conf t
router ospf 1
redistribute eigrp 100 metric-type 1 subnets
exit
router eigrp 100
redistribute ospf 1 metric 1544 2000 255 1 1500 ---Delay要除以10
distance eigrp 90 109 ----如果R2-R3是以太网就加这条命令
end
copy running-config startup-config
R3:
en
show int f0/0 --------查看BW Delay MTUd等
conf t
router ospf 1
redistribute eigrp 100 metric-type 1 subnets
exit
router eigrp 100
redistribute ospf 1 metric 10000 100 255 1 1500 ---Delay要除以10
end
copy running-config startup-config
在R1上ping 172,16.100.1可能会出现ping不通,或者用show route ip
新题 战报
An IPv6 overlay tunnel is required to communicate with isolated IPv6networks across an IPv4 infrastructure. There are currently five IPv6 overlay tunnel types. Which three
IPv6 overlay tunnel statements are true? (Choose three.)
A. Overlay tunnels can only be configured between border routers capable of supporting IPv4 and IPv6.
B. Overlay tunnels can be configured between border routers or between a border router and a host capable ofsupporting IPv4 and IPv6.
C. Cisco IOS supports manual, generic routing encapsulation (GRE), IPv6-compatible, 4to6, and Multiprotocol Label Switching (MPLS) overlay tunneling mechanisms.
D. Cisco IOS supports manual, generic routing encapsulation (GRE), IPv4-compatible, 6to4, and Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) overlay tunneling mechanisms.
E. An manual overlay tunnel supports point-to-multipoint tunnels capable of carrying IPv6 and Connectionless Network Service (CLNS) packets.
F. Overlay tunneling encapsulates IPv6 packets in IPv4 packets for delivery across an IPv4 infrastructure.
选择题: BDF
记得有一道新题是说IPV6的IPV4兼容地址转换的,例如::AC11:AC11和化成点分十进制表示的哪个是一样的,答案是::172.17.172.17,是不是较为简单啊。。。 IPv6 Virtual Link 这题的环境_不允许ping命令验证_可用show ipv6 route_或者_show ipv6 ospf neighbor替代
这次遇到的新题和需要注意的地方:
①:有道选择题改变了问法,问的是RTB的状态,所以选FULL/DROTHER。
②:新托图题,选3456,绝对没错。
Implementation Plan for an ospf Project.
1. Local preference value
2. Update query boundaries
3. Summarization boundaries
4. Ospf process ID that will be used
5. Authentication type that will be used
6. ospf Area and associated prefix
7. load sharing method that will be used
8. Amount of bandwidth that will allocated to ospf.
③:实验题中的EIGRP STUB没有抽到。
其他四道,只有IPv6 OSPF Virtual Link Sim可以copy run start,其他的都无法保存,但是没关系,你照敲就是了,一定要敲。EIGRP OSPF Redistribution Sim,这道题,跟考试稍微有点不同,R2与R3之间是以太网链路,题意要求最大带宽,一定记得在R2的EIGRP进程里敲上distance eigrp 90 109。
④:托图题
stub————————————————>CIR 256kb 信息速率256kb

新题:642-902
Which two descriptions about 6to4 tunneling are correct? (Choose Two)
A. Prepending a reserved IPv6 code to the hexadecimal representation of 192.168.0.1 facilitates 6to4 tunneling.
B. 2002::/48 is the address range specifically assigned to 6to4.
C. Each 6to4 site receives a /48 prefix in a 6to4 tunnel.
D. Prepending 0X2002 with the IPv4 address creates an IPv6 address that is used in 6to4 tunneling.
Correct ans = C & D Which is spread through out the AS — local pref
Which is used by router if route has more than one exit —- weight
Which is not propagated in updates—-weight
Which goes to other AS—-MED
跟题库类似的RTC,考试问的是RTB,选full/other
实验题除了EIGRP STUB都考了,注意IP地址有变,PBR的时候看清楚指下一跳的地址
重分发,先SHOW下接口参数,我的不是题库的10000K,100了,是100000 10 255 1 1500 场景题 eigrp:show ip eigrp topology all-link 在Core1 场景题ospf:show ip ospf 在D1 |
