JNCIP- EBGP peer-filter

IOS2JUNOS

working on the EBG Pcase study..i configured and applied the peer-filter-in and i see the following output on r2
root@r2# run show route receive-protocol bgp 10.0.5.254
inet.0: 54 destinations, 62 routes (50 active, 0 holddown, 5 hidden)

* 120.120.69.128/25 10.0.5.254 1492 I

and i see these being advertised out to r3 and r4 with correct prepend and local pref. Here's the output showing advertisement to r4.

* 192.168.100.0/24 Self 100 I

but on R4 it's showing that these routes are looped and not installed..i enable keep all knob to see these

R3 and R4 both configured same way...type internal;
local-address 10.0.3.4;
advertise-inactive;
cluster 1.1.1.1;
neighbor 10.0.3.3;
neighbor 10.0.6.1;
neighbor 10.0.6.2;

not sure what's going on..any pointers would be appreciated..thanks

Could you post R1,R2,R3 and R4 configuration.. Also just about wondering why you have a prepend 65412 twice... I do not recollect anything like that...

show route protocol ospf from R4 and R2 would also be nice..

the task requires that as should be prepended twice. here's the task

"Prepend 64512 64512 to all routes received from P1. Ensure that transit providers do not
receive these AS numbers."
i will post the config shortly

IOS2JUNOS

i'm using ex-4200 for r1 and r2 so the config is pretty long..i'm just posting the routing replated config. let me know if you need more. i also using this as c1, c2 and t2

you local as is 65412, and you prepend 65412!!
this is the problem.
you should prepend 64512 64512



Guess you are going to take the JNCIP exam next week BJ?

hoogen82

Well like Rabeen pointed out... The issue is with your AS number... Also I guess there are some RR license issues..

hoogen82

Don't be hard on yourself for not picking up the information correctly... Most of us did the same thing...I mean I had the same fault when I did this lab..

thanks hoogen...this forum is awesome..

IOS2JUNOS

changed to correct AS and it works now..RR license is just a warning...at least in 8.x junos..i had 9.5 loaded and it would bring the neighbor up because of the license..

thanks guys

Oh, since you are asking questions a lot recently, I thought you are going to take the lab next week. and the next week lab is held in Beijing China^^^^

This got me so puzzled,
Good Catch Indeed...
I saw it in this thread, and got registered to the site just to say:

THANK YOU


I am appearing in the exam on 3rd of April 2011

wish me luck

APA

Am I missing the point of this lab here?

Why would AS 65412 prepend 64512 to a route receive from AS 1492 - you should be prepending your AS to a route not a completely different AS number....

Otherwise you could have just configured something to the equivalence of ´allow-as in´ to achieve the same outcome without the bogus AS prepend...
