unit 20 not supported in fxp0 in juniper olive qemu

vishalsable

hi,

I am preparing for JNCIP examination, i have installed olive in my PC, thanks to blog inevitable olive for JNCIE.

I am running olive with 2 logical routers, logical router R1 and logical router R2.

but i am facing a problem that when i am assigning IP addres to fxp0 with unit 20 vlan-id 20,
during commit the router gives an error as

[edit]
root# commit
[edit logical-routers R1 interfaces fxp0]
'unit 20'
Only unit 0 is valid for this interface
error: configuration check-out failed

[edit]
root#

Please help me.

good call rossonieri

To add to what rossonieri said, fxp1-7 will allow you to specify other logical units then 0 so this restriction just pertains to fxp0.

root# commit
[edit logical-routers R1 interfaces fxp0]
'unit 20'
Only unit 0 is valid for this interface

just an addition, how about doing some "commit check" prior to push that "commit" button?
and after that - how about some "commit confirm"?

and, do remember that aldur hahaha, just kidding buddy

vishalsable

Thanks for the solution,

also, before commiting I have checked commit check, same error.

rossonieri#1

hi,

also, before commiting I have checked commit check, same error.

of course - it (the commit check" button) will prompt you the same warning/error message as that from the "commit" button command

the benefit is that it (the "commit check") will allow you to review your config modification as if it was being executed, either correctly configured nor false. its output? you decide what to do next

HTH.

hi,

I have created two logical routers R1 and R2.

Logical router R1 has set interface fxp1 and Logical router R2 has set interface fxp2.

but i am not able to ping each other.

Please see the confiuration.

Please help me i am not able to ping.......

rossonieri#1

hi there,

very nice
now that you have playing with LRs - what an improvement

Please help me i am not able to ping.......

ok, here is the thing - since you're on JNCIP prep now,
from this output :

interfaces {
fxp0 {
vlan-tagging;
}
fxp1 {
vlan-tagging;
}

you should be able to troubleshoot the error - how come you're not able to ping from R1 using fxp1 to R2 using fxp2,
let us know if you still having hard time to configure

cheers

ha, I had to have a double take to see what you were talking about, then was like ohhh yea, i see what's missing

Lets sit back and see if the OP can figure it out from the hints you gave

aldur,

dude, july 17th is about a month - you dont want to get messy with the proctor do you?

Lets sit back and see if the OP can figure it out from the hints you gave

ok, i'm out of VIP ticket - but, i dont mind if you have a spare one?

hahaha ... just kidding mate

i like this joke thing

ps : that popcorn looks good btw

Aldur

lol, man I'm so fried from studying services and all the issues that i've be working with at work that i tend to not see straight these days. And yes the 17th is coming up soon, and yes, i am scared I do feel like i have a handle on services though plus I've got 12 days straight that I won't be working so I'll have some good time to cram

vishalsable

the problem u have said is correct,

Also i have configured R1 on fxp1 and R2 on fxp2,

I have tried various thing but i am not able to ping the 2 routers.

Please hep me out.....

hi vishal?

ok, here are some rules so we dont get confuse
1. when we say olive - then it refers to the olive hardware emulation
2. say 'jemu' then it refers to olive qemu instance

ok, which one is yours?
if you are using olive - make sure you've checked your NIC HW, cables etc.
if you are doing jemu - make sure you've checked your qemu settings, cables etc.

and of course - doing #run sh inter terse or #run sh conf interface will be helpful

and a little guide on doing ping on LR :
[edit logical R1]
#run ping logical R1 <destination_R2> source <source_R1> count <count>
#run ping logical R1 <destination_R2> source <source_R1> rapid

this is the configuration, but i am not able tp ping.

please help.....

Try specifying the same vlan for all of the qemu interfaces, and avoid using fxp0 altogether. For example:

jqemu.exe -L pc-bios -m 128 -hda OLIVE.img -serial telnet::2001,server -kernel-kqemu -localtime -net nic,vlan=1,macaddr=00:aa:00:00:01:01,model=i82559er -net tap,vlan=1,ifname=Tap1 -net nic,vlan=1,macaddr=00:aa:00:00:02:02,model=i82559er -net tap,vlan=1,ifname=Tap2 -net nic,vlan=1,macaddr=00:aa:00:00:03:03,model=i82559er -net tap,vlan=1,ifname=Tap3

Well, other than verifying that your Tap interfaces are in fact bridged together within the Windows host, the only other suggestion I can offer is upgrading from 8.1 to 8.4. I did encounter weird connectivity problems in 8.1 between logical routers that didn't seem to pop up in 8.4.

vishalsable

i will install 8.4 and check whether it will work or not....

hi vishal,

so i see. you're run it under windows. hmm, well that will be something to look at since i dont spend much time doing jemu under windows - probably aldur has something for you since he's the windows guy . and i dont exactly know how you do it back there - so its very relative here,

but btw, things for you to check - just like i said before :
- look at cluepon.net to see whether your junos version is supported for jemu?
- make sure you check your bridging config under windows, see if there are bridging loop on the switch, check if your bridge did correctly set up etc.
- try to check your jemu config - its a C-coded config - so case-sensitive.

from what i see, looks like either your junos version is not supported under olive, or
your installation was not a successful one, i dont know?

until then, good luck

hi rossonieri,

can i use qemu in ubuntu.......

rossonieri#1

hi vishal,

sure thing

vishalsable

can anybody tell me, where i can get junos 8.4 R software

I search lot of sites, but no luck.....

JUNOS is proprietary software so you'll need to download it from the Juniper website. Other means would be piracy

hey,

i have changed my junos as well
but no luck, can anybody solve the problem, is there any problem with the laptop.

I am using Dell latitude E6500.
