Routing Protocol recommendation for MPLS Network

I am in the process of building a 14 site MPLS network for voice and data traffic. The vendor installing the network has configured RIPv2 as the routing protocol. I am considering switching this over to EIGRP. Can anyone explain to me why this would be better or should I just stay with RIP.
Thanks

Hi Chip,
Its not very clear whether you are implementing a MPLS network or implementing a Network over MPLS for an end user with 14 sites.
1) If MPLS network then other IGP variants than OSPF and ISIS best avoided. Now if the choice is between ISIS and OSPF then my personal recommendation would be OSPF. And this decision is purely driven by Operational Considerations rather than any technical advantages. Since at the end of the day what matters is how easy it is to implement add delete or troubleshoot the network.
2)If for End User then it would not be right to recommend EIGRP or RIP or OSPF without knowing the current size & topology of each of these 14 sites, as well as the desired expansion plans. But if these 14 sites are the only sites and are all standalone branch sites connecting over MPLS VPN then RIP,EIGRP or OSPF can be implemented as per your and customer comfort.

Recommendations for XenServer network configuration on B200M2

We are just starting a XenApp / XenDesktop / VDI project at our company. I'm very familiar with VMware as that is the hypervisor we primarily use on UCS. I'll be using XenServer for this project though as the licensing comes with the Citrix licensing. Does anybody have a recommended configuration for the nics in a XenServer running on UCS B200M2's. The adapters in the B200M2's are the M81KR's so I was going to setup them up similar to how I setup and ESXi server.
That would be the following:
Management network (this would use the same native vlan that I use for the management network of my ESXi hosts)
1 nic on fabric A that doesn't failover for the management network (bonded with nic listed below)
1 nic on fabric B that doesn't failover for the management network (bonded with nic listed above)
XenMotion (this would use the same native vlan that I use for VMotion in VMware)
1 nic on fabric B that can failover to fabric A
Guest / VM Network (this I would use vlan tagging to add the appropriate networks for my desktops)
1 nic on fabric A that doesn't failover for guest / vm network connectivity (bonded with nic listed below)
1 nic on fabric B that doesn't failover for guest / vm network connectivity (bonded with nic listed above)
Could somebody offere some suggestions / recommendations on how they have setup there XenServers in UCS for VDI / XenDesktop?

Hey Russ, I have deployed XenServer on UCS a lot and here is our standard config that has worked for my customers.
2 vNICs for management, 1 on Fabric A and 1 on Fabric B
2 vNICs for VM traffic, 1 on Fabric A and 1 on Fabric B
If using IP storage then 2 additional vNIC for that, 1 on Fabric A and 1 on Fabric B
2 vHBAs for FC SAN, 1 on Fabric A and 1 on Fabric B
Make sure you have a BIOS policy that disables all of the Intel C-States

Need a product recommendation for small network

Hello All!
I just started a small computer and network consulting company (in addition to my "day job"). I work for a huge company with several hundred sites, all Cisco networking of course. I am also setting up a small network and computer consulting company to do on the side and will be dealing with small companies and helping them with their network needs. Anyway, I am looking for a entry level Cisco product because my Linksys just isn't going to cut it any more. I want to set up 3 servers and I currently have 5 static IP's from Comcast. I want something that would operate like a PIX515 firewall but that would obviously be overkill for what I am doing. I want the capability to set up port forwarding to the inside from my 5 external IP's. Wi-Fi isn't critical but would be a "nice to have" if it didn't cost too much more. What would be a good product for my needs? I want a NICE CISCO product but not an EXPENSIVE one, either. I am also interested in certification and possibly becoming a VAR soon. Any pointers would be much appreciated.
Thanks,
--GREG--

I would steer clear of the 500 express. Since you seem to be new to cisco products, I would use the opportunity and buy what most of your potential customers already have. Get yourself a pix/asa and a 2900 series switch as first poster suggested. If you are interested in certifications, you will need to learn the command line interface. The 500 express will do you no good as it is all gui. This is only my opinion of course. Oh, and did I see not expensive and cisco in the same sentence. :)

Book recommendation for Content Networking?

Hi,
Is there any books outhere on cisco CSS, GSS for a good readup?
I know there's a whole lot of docs fr univercd, but was wondering if there are actually books on these products?
Thanks.

Thank you for your book recommendation. This sounds like an excellent book for learning Flash. From the description on Amazon, the emphasis of this book is on learning Flash with just a little information about ActionScript 3. Perhaps there is enough ActionScript 3 information in this book to get a good foundation with ActionScript, to learn the terminology and syntax?

Any recommendations for free network scanning software?

I'm trying to find some software that will allow me to capture the IP and machine names of both Macs and Windows machines. I have about 40 computers at my work and I find that I don't have my list with me all the time of who's IP is for who. If the software could include printers too, that would be great. Free is always good.
Thanks!

This one works for me...

MPLS for small network

In the past we have always had point to point links between our 3 remote offices and our corporate office. We're now switching to a MPLS network for all four sites.
We currently use Cisco 1721 routers for our WAN. What protocol should we use for routing across this new MPLS network? I'm also looking for a document what else I may need to configure for this MPLS design on the router itself.
We will have 1721 routers at all sites.

Hi,
for you as a customer the most appropriate picture is: The MPLS VPN behaves like one single IP router interconnecting your sites.
In your case just consider your 4 1721 being connected to one ISP router. There is no MPLS specific config needed on your 1721, MPLS is only within your ISP network.
This means: you send IP routing updates from one site to the "MPLS IP router simulator" and the updates will be sent further on to the other 3 1721. You forward an IP packet to the "MPLS IP router simulator" and it forwards it as IP packet to one of your other 3 1721.
If you are not dual homed or using backups then RIP would address all your needs. Also static routing might be suitable and the most simple aproach in your scenario.
Hope this helps! Please rate all posts.

CE dial-in to PE. What routing protocol I should use ?

Hi,
Situation - CE connected to PE via some ethernet interface (primary) and ISDN dial-up as backup, so I need to use some dynamic routing protocol to distribute customers networks to other sites. Now I'm looking towards extended (triggered) RIP, but maybe there are better choices?
As I know, only triggereg RIP and OSPF supports 'on-demand' circuits, but OSPF isn't recommended as CE-PE protocol because it has no VRF awareness and we would have to run separate OSPF process for every VRF what isn't nice. This makes RIP only choice? Or there are another possibilities, maybe BGP ?

Hi,
over all there is static, RIPv2, EIGRP, OSPF, ISIS and BGP for PE-CE.
Well floating static alone seems no possibility in your case.
RIP and EIGRP have some issues when running on redundant links into the VPN (possibility of routing loops), which would be the case with backup active and primary coming back. Depending on the exact topology there might or might not be a workaround.
OSPF has to be run as separate processes. Might be tough on PE resources, depending on your exact setup details. Other than that it does the job.
eBGP with ebgp-multihop and static routes is an option. So eBGP doesn´t go down, just is directed over backup link in case primary is down.
Pick your poison! :-)

Path Selection for Routes Across MPLS Network

Customer hub site has two CE routers with two links connected to two seperate PE routers in the Carrier's MPLS network. At the customer's remote site one CE router on a single link is connected to PE router in MPLS network.
How can I configure the CE routers at the hub site to advertised the same network across the MPLS network to the CE router at the remote site? Also, how can I configure the CE router at the remote site to select on of the router as the primary and the other as secondary? Can I use local-preference on the CE router at the remote site to selected on path over the other.
I'm not sure if this makes any sense. Any help will be appreciated. Thanks

Even with multiple RDs for VRFs belonging to the same VPN, you still need IBGP multipath, correct? Multiple RDs is just to get around the RR restriction.
Also, you posted this message a while back:
"If you have many VPN customers all using the same addresses (most likely rfc1918), the fact that they have different RDs and that the PE prepends the RD to the prefixes exchanged between PEs will make the same prefixes different in the MPLS VPN core
cust1 advertises 192.168.1.0/24 with RD 1:1 therefore
VPNv4 prefix is 1:1:192.168.1.0
cust2 advertises 192.168.1.0/24 with RD 1:2 therefore
VPNv4 prefix is 1:2:192.168.1.0"
My test lab does not support the IBGP multipath command, and thus even with different RDs, it still only installs one best path.
I understand that RD = make unique VPNv4 routes in SP space, and that RT = what to import into the VRF. However, I am having a hard time visualizing the scenario with mutiple RDs for the same VPN for load balancing purposes. I am trying to understand the logic behind it.
Per your example, if both 1:1 and 1:2 are received by the remote PE, assuming IBGP multipath is enabled, why would the remote PE load balance between the two links? Why would it assume that the hub subnets are reachable via two different PEs, and that it's not two different, isolated VPNs altogether?
Is it b/c you imported both 1:1 and 1:2 into a VRF at the remote PE?

L3 mpls network with out P router, all PE to PE plus daisy chainging

Guys, is it possible to run a core l3 MPLS network over 7600s and 3800s with out any P routers? The reason i aak is because of the particular situation where we will have to daisy chain PE routers due to lack of fiber.
any thoughts?

As martin says absolutley limited problems with this it will work a charm UNTIL yo urun into scaling issues. You are daisy chaining all the PEs which would also suggest to me that you are daisy chaining your RRs. In an mpls network the RR's have enough state to handle to keep them busy enough without also having to deal with passing labels about the network. Also you will have any cisco account team breaking down your door putting the fear of god into you for not having at least 2 P routers ;-). So yes you can indeed run it like you say but the lifetime of your network will be very limited indeed. If your not an SP then dont be concerned - unless you are an enterprise with 10000000s routes then id start to worry. Oh they (cisco) also state that PEs also have enough to do in their life without passing labelled packets about the place. sit and think about what your poor PE is having to do daily it could be 100 vrfs routing tables, which in turn means layer 3 lookups to find out where the packet has to go, qos, multicast, bgp, ospf, rip, eigrp, your own internal IGP, TE tunnels, RSVP - this poor router has enough to do without also adding transit traffic. ;-)

Full mesh VPN solution for on MPLS network with PE and CPEs

Hi,
We are trying to evaluate some best solution for Hub-Spoke mesh vpn solution in a MPLS network. The VPN hub router will be in PE router and all the VPN spoke will be in CPE.
Can someone please let us know what will be the best vpn solution, we understands that there will be some technical limitations going with GETVPN but still we did counld find any documenation for possiblity of using DMVPN.
How about the recent flexvpn, can fex-vpn work on this requirement, where can i get a design/configuration document.?
thanks in advance.

Hello,
GetVPN is intended for (ANY-to-ANY) type of VPN communication, over an MPLS network with Hub and Spoke Topology, your best Option is to look for Cisco (DMVPN) implementation where this type of VPN is primarily designed for Hub & Spoke.

Routing protocol over mpls

Hi all,
i have to implement a network customer over a vpls provider ( 60 site L2 any to any).
which protocol for this design ? eigrp, ospf or bgp with advantage or inconvenient?
thanks,

If this is to be a layer 2 network for 60 sites with any to any connectivity then you can choose which ever routing protocol you wish since the provider will not be participating in the routing protocol. BGP would be at the bottom of my list for this for several reasons, one of which is that BGP does not do dynamic neighbor discovery and I would not want to manually configure 59 neighbors on each of 60 routers.
Either OSPF or EIGRP could be good choices. If we knew more about this network it might be possible to favor one or the other. For OSPF it seems likely that you would have a single area and some people might be concerned about 60 peers in a single area. But I think it could be appealing that most routers would go through full adjacency with only two peers where with EIGRP each router would negotiate neighbor relationship with 59 neighbors. Another consideration might be what the topology of the sites is like. If each site has several subnets and if the subnets fall into summarizable ranges then EIGRP might be preferred since it enables summarization from each of the routers which reduces the complexity of the routing table on each neighbor.

Routing to MPLS network

Hi,
We have several branch offices connected via a managed MPLS network. Each MPLS router in the branch office is connected to the local LAN switch, with its separate firewall and internet access router. How do we direct traffic from the local network (unmanaged) to the private IP addresses in the MPLS network (managed)? Can static routes be configured on the ASA5505 firewall to route traffic to MPLS router?
ISP router>local router>ASA5505 firewall>LAN switch>MPLS router>MPLS cloud.

Said
Is the LAN switch layer 2 only or layer 3 capable. If you do not have access to the MPLS router you have 2 options
1) Add a route on the ASA for the private MPLS networks pointing to the MPLS router. You will need to enable hairpinning on the ASA.
Set the default-gateway of the clients on your LAN switch to be the ASA.
2) If your switch is a Layer 3 switch then you can do this in a much cleaner way. Create the L3 vlan interface(s) for the client vlan(s) on the switch and then you can use statics on the L3 switch eg.
ip route 0.0.0.0 0.0.0.0 "ASA inside interface"
ip route "MPLS private net" "subnet mask" "MPLS router inside interface"

How to connect a E1200 wireless router to a machine tool network for wireless communications

Hello all, I am new to the forum, hope someone can help me out. I am wanting to connect my E1200 wireless router to a machine tool in our factory that has programmable controllers and is connected to the machine components via ethernet connections. This is so we can troubleshoot the machine without having a wired laptop. We have several ethernet switches on the machine and a range of IP addresses say from 192.16.1.1 through 192.16.1.150, and 192.16.17.1 through 192.16.17.150, all of the addresses are not used but random addresses in the range. I would like to be able to connect my E1200 to either one of the networks without having to make a change in the router setup. I can make it work on either network but when I switch my cable to the other network it has to be reconfigured. I am currently connecting my data cable to a ethernet port on the router and changing my router address from 192.168.1.1 to 192.16.1.1 and selecting a range of 150 so it will assign numbers as needed. This works great until I change to the other network and I have to change my router address to 192.16.17.1, I know this can be done on some routers because the technicians from the machine builder use them when working on the machines. thanks

On the basic setup tab make the changes shown below:
This basically make the router disappear off the existing networks and turns it into a wireless AP.
Then when you set your laptop's wireless adapter to whatever IP network you want to connect to.
If you need to connect to your router again change the laptop's adapter IP to something like 192.168.200.2
Keep in mind nothing ever gets plugged into the Internet Port on the router.
What I do with these manufacturing machine's is put them on the company network with static IP's. Then so operators can transfer programs and view drawings I place ELO touchscreens at each location. For the Laser cutter operators that do nesting they have a desktop workstation for the CAD software and put the nests on a network share or direct to the laser cutters.
Please remember to Kudo those that help you.

I'm currently signed onto my home network and want to go on with another computer but don't remember my password for my network. Does anyone know where to find this? It's a password that I set myself, not the one that came with my router.

I'm currently signed onto my home network and want to go on with another computer but don't remember my password for my network. Does anyone know where to find this? It's a password that I set myself, not the one that came with my router.

It's in your Keychain on the computer you usually use to connect to your network - the "kind" will be "AirPort Network Password".
Your Keychain can be opened by using the Keychain Access program. It is in your Utilities Folder.
Open Keychain Access, and type airport in the search field. You will see a number of entries. Choose the one with the name of your wireless network, open it, and check the box next to "show password". Before it reveals itself you will be asked for your login password - the one you use to log in to your MacBook.
The network password will appear in the box.
Quit Keychain Access.
