Hi there,
I guess your provider NAT'ing IP addresses of your servers somewhere in
cloud.
Try to lower the arp timeout at core routers by applying the below command;
arp timeout 1800 ------> default 14400 seconds (4 hours)
This will give you some time to fix the problem and/or to understand what is
happening.

Subject: please i need your hep! !! !!! !!!!
Please i need help from you guys.
My orgainisation is a Finacial institution with over 140 branches with 7
service providers providing links.The 140 branches were distributed btw the
7 vsat providers terminated at the datacenter.Each provider has the remote
branches terminated on a router before entering a core switch.so making 7
core router routers.There is a finacle application server being the core
banking application server.Route of each branches were added on the server
pointing to ip address of each provider's core router as its gateway for
remote branches to communicate with that server.
Recently last 7 days i just discovered that braches will refuse to access
that server despite that can ping the gatway in datacenter core router .I
found out that once i clear the ARP cache on the core routers in datacenter
they remote branches will continue to communicate with the server.
So i now need to clear ARP cache every 3o mins on the routers for them to
ping the servers.
please try and help me out.please what is going wrong and what can i do?
