Slow network performance while using TFTP

[enriquebs]

HI all,

The thing is that TFTP traffic goes really slow while crossing our MPLS/MP-BGP network, at present I?m trying to upload an IOS image (25MB) to a remote PE and it seems to don?t finish untill more than 1 hour...

Here is the output of the "copy tftp: disk0:" command:

Loading c7300-k91p-mz.122-27.SBC5.bin from 172.26.26.99 (via GigabitEthernet0/0): !!!!.!.!!!..!!!.!!!.!!!!!!!!...!!!.!.!!!!!.!!.!.!!!!!!!.!!!!.!!.!!.!!!!!!.!!!!!!!!!!!.!!!!!!!.!!!!!!!!!!!!.!!!.!.!!.!!.!!!!.!!!!!!!!!!!!.!!..!!!!!!.!!!!!!...!!!.!!!!!..!!..!!!..!!.!!.!!!.!!.!!!!!!.!!..!!.!!..!!...!!!.!!!!!!..!!!!!!.!!.!!.!!..!!.!!!!!!!!!!!!!!!.!!!!.!!..!!!!!!!!!.!!!.!!!!.!!.!!!.!!..!.!!!!!!!!.!!.!!!..!!!!!.!!!!.!!.!!..!!.!!.!!..!!..!!!!!!!!.!!.!!..!!..!!!.!!!.!!..!!.!!!!!!!!!!!!!!!!!.!!.!!.!!..!!.!!..!!.!!.!!.!!!!!.!!!!!!!..!!!..!.!!!.!.!.!!!!.!!.!!.!!.!!!!!.!!.!!.!!.!!!!!!!!!..!!!.!!!.!.!!!.!!..!!!!!!!!!.!!!..!!.!!.!!!!!!!.!!!!!!!.!!!!..!!..!!!!!!!!.!!!!!!.!!!!!!.!!!!!!!!!..!!..!!!!!!!!.!!!!!!!.!!!!!!!.!!..!!!!!!!!..!!!!!!!!!!!!!!..!!!!!!!!!!!!..!!!.!!.!!!!..!!!..!!!!!!.!!.!!!!!.!!!!..!!.!!.!!!!!.!!!!!!!!.!!!!.!!..!!.!!!!..!!.!.!!.!!!!!!.!!!.!!!!.!!.!!.!!.!!!!!!!.!!!!!!!!!!!.!!!!.!!.!!!..!.!!!!!.!!.!!.!!!!.!!.!!!!!!..!!.!.!!!.!!!.!!.!!!!..!.!!!!!!..!.!!.!!.!!!!!.!!!!!!!!!!!.!!.!!!!!...!!!!!!.!!!.!!!!!!!!.!!.!!..!!!!.!!.!!!!!!!!..!.!!..!.!..!!!.!!..!..!!.!!!!!!.!!!!!.!!!.!!.!..!!!!.!!!!!!!!..!!.!!!!!!!..!!!.!!..!!..!!!.!.!!!!.!!!!!.!!!!.!!.!!.!!!!!.!!.!!!!.!!.!!.!.!!!!!!!!!!!!.!!!.!!!!!!!!.!!!...!.!!!.!!.!!!.!!!!!!.!!!!.!!.!!.!!.!!.!.!!!!!!!.!!!.!.!!!.!!!!!!!!!.!.!!!!.!!!!!..!!!!!!.!!.!!!!!!!!!!!!!.!!.!!!!!.!!..!!.!!!.!!.!!!.!!.!!.!.!!!!!!!!!!!!.!!!.!!!!.!!!!!!!!!!.!!.!!.!!!.!!.!.!!!!!!.!!!..!!!!!!.!!!!!!!.!.!!!.!!!!!!.!!!.!.!!!!.!!!!!!!..!!!!!.!!!..!!..!!.!.!!!!.!!!..!!!!!!!!!!.!!!!..!!!.!!!!!..!!.!!!!!!!!!!!!!.!!!!!!!!!!!!!!!.!!!!!!.!.!!!.!.!!!.!!!.!!.!!.!!..

and so on......

Has someone experimented something like this?

Thanks in advance,

Everything looks good, cpu is arround 10% and no errors in the interface, and the same for the other two routers in the path.

I?m thinking the problem coud be related to asymetric routing...

Is your provider Prioritizing your traffic. Where tftp is getting classified as normal traffic and voice and critical applications are getting a higher priority? Also, what is the distance between your locations?

No, anyway there is no traffic in the network, it is not in production, so, there is no load and this traffic can?t be discarted
