Hi, i have setup the saprouter on NT and the service is running. i have also maintained the saprouttap. i can ping the sapserv2 from my saprouter.

i have also maintained the services file. i then entered my internal IP of the saprouter in transaction code OSS1 to create the rfc in sm59 automatically.

in SM59 on my DEV system, i get a connection test error, saying:

Error: Network Packet too big

Location: SAProuter

Detail: NiBuffin: massage length 892678176  exceeds max

Component: NI

Module: nibuf.cpp

on saptouter: dev_rout

ERROR NiBufin: massage length 892678176 exceeds max ( 8388608; hdl 2;peer= 194.39.131.34:3299)

can anyone please assist, highly appreciated 

regards

Steven

Hi,

I think that you need to check the network settings using the below note.

Note 500235 - Network Diagnosis with NIPING

What is the version of the saprouter and NIping in your system.

Thanks

Hi Steven

Are you able to telnet <ip address> 3299 and also can you paste the complete logs dev_rout.It is most likely to be a network/firewall problem .Check with NW administrators.

Hi,

Please check the below note. It looks to be a network issue. have you raised a message with sap to register your router.

Note 1512705 - Work process hangs during RFC communication

Workaround:

This error only happens when the network connection to the target host is unstable. Working in a stable network environment will eliminate this issue.

Why did you install an old version of saprouter. you could have insatalled saprouter 7.20.

Thanks

Hi Steven,

Looks like some packet size limit has been defined on the Network.

Could you connect with Network team along with this error message.
