Do you lose CCNP/CCDP certifications right at the expiration date or is there a grace period similar to CCIE's (one year grace period)?
Thanks in advance,

Does anyone know if there's any simulation program on which I can practice MPLS L2VPN's (VPLS, pseudo-wires AtoM etc...) on IOS -XR? I did some research on VIRL, GSR1000v and Cisco Lab Builder and I am still not sure if any of those platforms support L2VPN's on IOS-XR. I know IOU probably supports it, but I know nothing about UNIX and it is not legal to use outside of Cisco. GNS3 does have the option for XRv but I doubt it will support L2VPN's. Thanks in advance,

So my friend asked the instructor what kind of software that is and he said it was CSR1000 running on VMware. Is that similar to VIRL? Man yesterday I had not idea of the name now there's too many of them lol: GNS3, IUO, CSR1000, VIRL.

Thanks for the explanation. I already hold CCNP and CCDP so I was thinking more for CCIE studies, since the real lab i snot cheap, plus draws lots of power and is very noisy when you run it in a average room in a house. But I'll definitely check some of the options you mentioned.

Today a friend of mine showed me some kind of Cisco network emulator that uses real IOS. It is not GNS3. This thing does switching and routing flawlessly. It was running on a virtual machine on Linux. He said that Cisco is using it to train their employees and for lab mock ups. It looked way better than GNS3. But for the life of us, we cannot figure out what its called and if you can purchase it. When we log into the router and do show ver, I can see it is using a real IOS calling it from a directory that is running on a Unix machine. But we can't see any names or logos or can't figure out how it's setup. The school gives my friend remote access to that software. Any guesses what this software is called? Thanks in advance

I have been working on a pretty big project for work for the past few months and today I am getting errors when I try to open my project. Hopefully I did not mess it up because I've spent so much time on this project and deadlines is nearing. Hopefully I won't have to re-create the whole topology from scratch. Errors I am getting: => *** Warning: Connecting SW1 2 to access 800 Infotek_R3 f0/0 resulted in: nonexistent device Infotek_R3 *** Error: errors during loading of the topology file, please correct them *** Error: 208-unable to find object 'ACR2NE' Both of those devices are part of my topology and I need them, but I've tried editing topology file and removing references to both just in case, but that resulted in even worse errors: DynamipsError: 208-unable to find object 'CCR1SW' DynamipsError: 208-unable to find object 'DTR1SW' and so on... for every device! I do have backup of all configs but I really don't want to create topology again with all colors and links and then paste configs. It would really take me a long time. So any help on this is appreciated. I am including my topology file.

Yeah I totally forgot about that. I fixed it now. What I did was I tagged the route with additional community since it has to be there anyway, because I will be using it again and again through out the topology. It works now Thanks for your help.

Your syntax worked. But then I've tried to go back to mine (standard one) and it worked too. I've cleared sessions few times just to make sure it will still hold, and it is. However now when I want to try to add more communities to it (ex. ip community-list standard REGIONAL-AGGS permit 300:61100 300:61101) it will not work. It has to be some bug or something. Thanks for the help.

Thanks for the reply Harold. Interestingly enough nothing shows up even though route map is there and is applied to the neighbor. R2# show ip bgp route-map L3-TEST R2# I've cleared BGP sessions multiple times. I am clearly doing smething wrong or GNS3 has a bug.

This is all done in GNS3 and it got me stumped so any helps is appreciated. I am trying to advertize only certain routes (24.1.0.0/20) from R1 to ISP via ip community-list but for some reason ISP is not seeing 24.1.0.0/20 the route. Explanation: R1(AS20)—R2(AS20)--> ISP(AS10) R1 and R2 are in the same AS and are directly connected. 24.1.0.0/20 is generated on R1 via aggregate address and tagged by community 300:61100 , and then passed down to R2. R2 sees the 24.1.0.0/20 route as well as its community as you can see from the output: R2#show ip bgp 24.1.0.0/20 BGP routing table entry for 24.1.0.0/20, version 9 Paths: (1 available, best #1, table Default-IP-Routing-Table) Not advertised to any peer Local, (aggregated by 20115 96.34.15.2) 96.34.15.2 (metric 3550) from 96.34.15.2 (96.34.15.2) Origin IGP, metric 0, localpref 100, valid, internal, atomic-aggregate, best Community: 300:61100 But for some reason it won’t pass it to ISP. On R2 I have following config: router bgp 20 neighbor 8.4.4.6 activate neighbor 8.4.4.6 send-community neighbor 8.4.4.6 route-map L3-TEST out ! ip community-list standard REGIONAL-AGGS permit 300:61100 ! route-map L3-TEST permit 10 match community REGIONAL-AGGS Without the route-map ISP of course sees 24.1.0.0/20 (and everything else) because everything is allowed. But I just want to pass that specific route to the ISP router. What am I doing wrong with this route map? Note: I do have send-community command on all routers. Any help is appreciated.

I've been working for an ISP for 10 years already, and I am trying to gain experience in enterprise networking. As title suggests, I am looking for some real world "detailed" case studies how network is desgined in medium-large business. I know Cisco has some in PDF format but they are very brief without much details. I'd like to see specific products used, infrastructure and how. Maybe even operational costs and some sample configs. Basically as detailed as possible. Are there such a things? Thanks in advance

Thanks for the reply. I did not know that RIB failure is not an issue. That makes more sense now. Because no matter what router I used to advertize those interconnects with, I would have encountered RIB failure.

Thanks for the reply Akash. If I don't advertize those interconnects into BGP, then R1 and R2 won't be able to reach 192.168.63.0 and 192.168.64.0 networks. But if I do advertize them then I am runing into another probolem: On routers R1 and R2 I am getting RIB failure because those networks are now known via BGP instead of directly connected. R1: R1#show ip bgp rib-failure Network Next Hop RIB-failure RIB-NH Matches 192.168.31.0 192.168.31.3 Higher admin distance n/a R2: R2#show ip bgp rib Network Next Hop RIB-failure RIB-NH Matches 192.168.42.0 192.168.42.4 Higher admin distance n/a on R6 as well R6#show ip bgp rib-failure Network Next Hop RIB-failure RIB-NH Matches 192.168.63.0 192.168.63.3 Higher admin distance n/a 192.168.64.0 192.168.64.4 Higher admin distance n/a
