This is Simlet
http://www.rstut.com/ccie-written/labsim/ip-ospf-database-sim#comments
passed today with 1000/1000
There is some confusion on this sim and what it is. So I will tell you that it is a window with 4 squares on the left side. Click each one to see the question. Again, there are 4 questions and one topology. Click the ‘topology’ button at the bottom of the sim to see it. There is only one topology for all 4 questions. You do NOT log into any routers. All configuration is provided as text in the question.
Topology – Note that the topology on the following line is simplified as there are other routers in the real topology but only the routers listed below are in use.
R6(BGP AS40) —-> R3(BGP AS1000) —–> R2(BGP AS10)
Question 1 BGP – Look at the configuration in R3. Of the following routes (30.30.0.0/16, 40.40.0.0/16, and 200.200.0.0/16) Which ones will show up in R2?
Relavant R3 config is the following:
router BGP 1000
neighbor {R2 Loop IP address} remote-as 10
neighbor {R2 Loop IP address} route-map BGP out
neighbog {R2 Loop IP address} send community
route-map 5 BGP permit
match ip address 1
set community no export
route-map 10 BGP permit
access-list 1 30.0.0.0 0.255.255.255
Answer – 40.40.0.0/16 and 200.200.0.0/16 will show up. 30.30.0.0 will not be sent to R2 because it is now in the community of ‘no export’
Question 2 QoS – Which statements are true about the following policy map:
R1#show service-policy Gig1/0
Class Somename1 Match-All
ip dscp 40
match packets size 200 min 1000 max
NO match packets size min 500 max 500
Set IP Prec 2
Class Somename1 Match-All
match packets size 500 min 500 max
Set IP Prec 1
Class default match any
Answer…I forget the answers (there were 6 to choose from) but I believe I chose the ones that stated the following:
1.) packets between 200 and 1000 bytes will be marked with prec 2
2.) packets less that 488 will be marked with ip prec 2
3.) I forget what I put for this one.
Question 3 EIGRPv3 – Eigrp is not forming a neighbor relationship. Why?
The question then shows only the runing config for 2 interfaces on each router.
Answer – EIGRP needs to be enabled on BOTH routers. Do not select the option for EIGRP needs to be enabled on only one router because it is wrong.
Question 4 BGP – R6 is redistributing the following routes (30.30.0.0/16, 40.40.0.0/16, and 200.200.0.0/16) into BGP. Which ones will show up in the routing table on R2.
Now….this one was tricky for me as they provided no further configuration. So…I looked at the configuration for R3 in question 1 and deduced that R2 will only
have subnets 40.40.0.0/16 and 200.200.0.0/16
