BCSI Simulation question 1
- Thread starter mikeleahy
- Start date
Sadly, know it all isn't too far off the mark. I felt I got hit on: Rip v2, OSPF, BGP, policy routing, IPv6, and redistribution the hardest.
Didn't have anything on NAT or IGRP. Be sure you've gone through as many show commands and be able to identify various things from the show commands. Like the OSPF area type, eigrp FD and AD.
Good luck.

Hi Mike,
I passed the BSCI last week.
There was loads of BGP, a fair bit of ISIS, not really that much OSPF. lots of RIPv1 & v2. Know your EIGRP feasible successors etc, IPv6 is just limited to recognising the corerct address format and knowing that tunnelling is possible. Not a lot of NAT although it is still there. lots of redistribution, metrics, route-maps, PBR etc.
The sims were easy, no problem if you can setup a protocol and redistribute it.
Know your OSPF area types and route tables and you'll be fine. Good luck!

They love RIP as there is all this stuff about version 1 or 2 send/receive and what does it do when you redistribute a classful protocol into a classless protocol like OSPF etc. know this stuff inside out.
I was surprised about how much BGP was in there: all sorts of stuff like how the neigbours work, TCP hellos and need for static route to destination before peering, order of preference for metrics, output from show commands, states, lots of stuff. nothing too difficult, just lots of it. I forget the details now. I'm just in shock that I don't still have to read all those textbooks every day of my life anymore.
You'll be fine. just make sure you know redistribution and routemaps.

Your question is a bit vague, but I'll attempt to answer it. If you have a network statement under rip v1 for any 10.X.X.X (the x's can be anything, it doesn't matter) it will automatically convert it to the classfull 10.0.0.0 and advertise that it has a router to that. You can sit there and type 10.0.1.0, 10.0.2.0, ect, ect, but it will do nothing. If you have two interfaces (serial/ethernet/anything - it makes no difference) that are 10.1.1.1, and 10.1.2.1 or even 10.1.1.0 and 10.2.1.0, rip isn't going to recognize them as different networks. The local router it's self will route correctly, but rip won't and other routers will only see a classfull 10.0.0.0/8.
This is exactly the kind of thing you should know cold for the BSCI. I remember the BSCI being quite evil - they will never ask you if you should use ripv1 or ripv2. (Obviously, the best answer is ripv2) I never had a question like that on the BSCI - they think that's just too simple! They will assume you KNOW that ripv1 is the wrong answer, but they will want you to explain something else like would v1 work and why.
That is just an example of their evil thinking- I don't think they really asked me that exact question. To answer that question, yes, it would work as long as all 10.X.X.X networks were limited to that router and nowhere else - it would advertise a classfull 10.0.0.0. The other routers would send everything to that router and it would route things non classfully once it got there via the connected routes in the routing table. Does this answer your question?
Dang, I have the CIT on Wednesday and I can hardly remember this BSCI stuff - I'm in trouble!

sorry. i wasnt clear. i know all dat stuff well but one sample question was asking what interfaces would be sending and receiving rip updates when the network command was just
network 10.0.0.0 (serial int)
the ethernet interfacec wasnt included in the network command 172.16.0.0 but they said that it still sent and received rip updates even though 172.16.0.0 was not under the router rip command
network 10.0.0.0 (serial int)

The network command tells the router what network to advertise in a particular protocol, it will advertise them out all interfaces, unless there is a passive-interface command there.

S0 IP address = 10.0.0.1 /8
E0 IP address = 172.16.10.1 /16
Router RIP
Network 10.0.0.0
The broadcasts go out all interfaces but only advertise 10.0.0.0

Testking steals all their questions straight off the test. That does not mean testking knows the correct answer, nor does it mean those who pass using testking understand networking. I advise against using them.

I beg to differ. The 10.0.0.0 network is the only network statement so RIP will not do anything on the 172.16.10.1 interface.
For IGPs the network statement does two things: First, it tells the router what interfaces will run the routing protocol and Second, it tells the router what networks it can originate advertisements about. Therefore, only the interface that is in the 10.0.0.0 network will send and receive RIP updates. The 172.16.10.1 interface will not send RIP or receive RIP information and the 172.16.0.0 network will NOT be advertised into the RIP domain.
If you have any questions, put the config on a router and sniff the wire just to be sure.

Now that I think of it, Cluebird is right. The network statement in RIP defines the participating interfaces. The only routing protocol that doesn't do that is BGP - it's the oddball. I should have thought of this before; no wonder I didn't pass the CIT!
As for testking, I still advise you not to use it. If you can not pass the test using your own understanding of what you have read, you are cheating yourself. You will not understand the material as well as somebody who has not not used testking.

I have a important question about this topic below:
CertWays Q: 11
Router TK1 is configured as follows:
interface serial 0
ip address 185.64.1.1 255.255.255.0
!
interface ethernet 0
ip address 15.10.10.1 255.255.255.0
!
router rip
network 15.10.10.0
!
ip route 0.0.0.0 0.0.0.0 serial0
What result would the above commands accomplish?
A. RIP updates are sent and received on interface serial0 of the router.
B. A default route is sent to neighbors on interface serial0 of the router.
C. A default route is sent to neighbors on interface ethernet0 of the router.
D. RIP updates are sent and received on interfaces serial0 and ethernet0 of the router.
E. None of the above.
Answer: E
Explanation:
Since RIP is configured for only the network on the Ethernet segment, RIP updates will only be sent and
received on this network, not on the serial interface. In addition, static routes are not sent via RIP, unless the
"redistribute static" command is configured. This includes default static routes.
Note: Had the configuration command "redistribute static" been placed under the RIP routing process, then
choice C would have been correct.
