I didnt understand why we dont use 12 host bits?

View the exhibit. Currently the two eBGP links between AS100 and AS200 have an average inbound load of 65% and 20% respectively. After further investigation, traffic to 10.10.1.16/28 accounts for 45%, and traffic to 10.10.1.32/28 and to 10.10.1.48/28 each account for 20% of the inbound load. The BGP attributes are currently set at their default values in both autonomous systems.

If you want to influence how AS200 sends traffic to AS100, which eBGP configurations would you configure in AS100 to influence AS200 to use the eBGP links more evenly? (Select two.)



Your Answer:    route-map as_50 permit 10
                          match ip address 50
                          set metric 150
                          access-list 50 permit 10.10.1.32 0.0.0.240
                          neighbor 192.168.30.2 route-map as_50 out

Correct Answer: neighbor 192.168.20.2 route-map as_50 out
                          route-map as_50 permit 10
                          match ip address 50
                          set metric 150
                          access-list 50 permit 10.10.1.32 0.0.0.240



Explanation:
We want to reduce the incoming traffic on the 65% route and increase the traffic on the 20% route, by using mechanism that instructs EBGP neighbor in AS 200 to prefer more the path between routers F and B.
The MED is used to decide how to enter an AS. It is used when multiple pathways exist between two autonomous systems, and one AS is trying to influence the incoming path from the other AS. A lower MED value is preferred; the default set to 0 for Cisco routers. So what we want to do is raise the MED on a subnet on the 65% route in AS 100, that when advertised to EBGP neighbor in AS 200, it prefers the 20% route.
Since the 10.10.1.48 favors the 20% from router B route due to route cost,  and 10.10.1.16 favors the 65% route from router A due to the same reasoning, the subnet we should try to manipulate is the 10.10.1.32 because it is traveling the 65% path (20% +45%=65%). So lets raise the MED on the 65% path from router A to 150 so the lower MED on the 20% path from router B is preferred.
Step 1: Define the neighbor that you want to raise the MED to and the route-map you will use to do this:
Neighbor 192.168.30.2 route-map AS_50 out
Step 2: Write the Route map to raise Med to 150 and define the traffic associated with this route-map via ACL:
route-map as_50 permit 10
match IP address 50
set metric 150
access-list 50 permit 10.10.1.32 0.0.0.240
Now you have raised the med of a 20% traffic across the Router A route to the AS200. This traffic will now switch to use router B route as the preferred route due to lower MED. This in turn raises the traffic on router B to 40% (from 20%) and lowers the traffic on router A to 45% (from 65%).


Based on the explanation, shouldn't my answer be correct? Also the access-list entry wildcard mask should be 0.0.0.7 and not 0.0.0.240

QID:RTE140, For BGP, regarding the Exhibit,
I think the ACL that is referenced is incorrect.....
"match ip address 20"
And the ACL is "access-list 65 permit...."


And also::

Hands On Lab #4, OSPF Virtual Link
This has the IPv6 addresses.

I am confused by the Running Config between R2 and R3
They are configured w/ IPv4 Addresses, but yet show ospf for IPv6 enabled on the interfaces.
I don't think it will work that way.

Can anyone smarter than I, shed some light on those two problems??

When I was practicing for the simulations on the CCNA I used Packet Tracer, a bunch.  Now it's time for the CCNP and Packet Tracer doesn't support many of the required commands .  I have seen a few references to GNS3, checked out the web site, they say I will need an IOS file.  I am familiar with IOS files, I also know a CISCO IOS is a closely guarded item.  I asked my CISCO instructor about it, turns out I got a better chance at sleeping with his wife.  My question is, for you guys/gals running GNS3, where are you getting these IOS files.

Hello
Anyone helps me please i want Immediately

If help you than thank you for this.

Just trying to pass on the love.  I have a CCNA lab kit which consists of two 2610 routers (2 wic1-t & DB60 Back to Back cable, Console Cable) and one 1924 switch on Ebay for $230 OBO  free shipping if anyone is interested the link is below

i used www.pass-guranteed.com website for preparing my exam
but there are all material fake and old
all material is useless on this site
don't waste ur money or time on there

Took my CCNA test and passed.  Thanks to how2pass.  Those studying for the CCNA, review and study the question and answers on how2pass and I guarantee you will pass. Very similar.  ;D

I think I either found a typo on this question, or need some clarification on it.  The Question states:

-That AS 65500 is not advertising the prefix 192.168.12.0/22
-OSPF is being used as IGP
-Which addition will advertise the prefix?

- I answered "redistribute ospf 1" which now i think is a gotcha because the question never tells you which process ID OSPF is running on, but I answered that because you can redistribute OSPF routes into BGP.

BUT

-The answer listed as correct puts a static route to null0 at 192.168.12.0 but with a mask of 255.255.255.252 , which is a /30 and not a /22. If it was a /30 then BGP would not use this route to advertise to its neighbor because the specific prefic must be in the routing table, correct?

BTW, I'm taking my test tomorrow.  I will post my results when I get them.

Has anybody taken the ROUTE part of ccnp? Just wondering how the hands on part was going to be? How many questions and is it pretty close to the how2pass website?
