MPLS based on OSPF (GSR platform) [7:34268]
Hi all, I have to deploy MPLS based on OSPF as IGP, the backbone is build on Cisco 12000 GSRs (12008,12012 & 12016). I heard that MPLS over OSPF on GSR can cause some problems (ISIS is prefered as IGP ...) but I don't have details about these problems. Does anybody experienced bugs with this kind of environment ? Thanks for your help.

if you have a CCO login account, the following TAC link might be a good place to start: http://www.cisco.com/warp/customer/105/mpls_index.shtml I also did a quick search on "12000". Is it my imagination, or are there a LOT of caveats / bugs on that device and it's cards?

Hi, The best advise to you is you would be better to check all that with your Cisco account team. Because the 12000 series and its cards support different features and depending on what you are using, some features may or may not be supported... As far IS-IS vs OSPF, with IS-IS you can put more routers in a single area. Can be 200-400 routers and even more where OSPF the rule of thumb is about 60-80. Since "Traffic Engineering" (TE) is not supported yet through areas, IS-IS was the choice to made. But I think it will be supported very soon so it may not be an issue for very long... Frank S.

It is my experience that the opaque LSA implementation on the GSR is riddled with weird errors, especially for inter-vendor operability, but also other key OSPF functionality (opaque LSA's sometimes don't get flooded properly, opaque LSA's were not properly refreshed, sometimes errors with checksums and sequence numbers, etc.). Some of the problems were fixed lately, but I still recommend sticking with ISIS. > ""Stephane LITKOWSKI"" wrote in message > [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > > Hi all, > > > > I have to deploy MPLS based on OSPF as IGP, the backbone is build on Cisco > > 12000 GSRs (12008,12012 & 12016).

There are absolutely a lot of bugs and caveats on the 12000. Hence the popularity of the Juniper M40/M160. Service providers want a core router that doesn't spontaneously reboot every week or so.
