Hi
When traffic is passed via the GRE Tunnels packets are dropped.As the bandwidth are unequal I am using EIGRP
Currently running EIGRP between Tunnel routers and OSPF between VPN Router to Core. Physical links are ok, no error on interfaces.
If I run only tunnel at sales_office then no drops. load sharing is required on two tunnels. i have plugged the configuration to the post.
Once drop concern are fixed will add IPSEC to it.
please do input

I would request you to apply the tweaks on the tunnel interface and see the results.
IP MTU 1400
IP Tcp adjust−mss 1300
There are issues with IOS .
But we need to correct the configuration part first.
In my experience I would say not to use unequal cost load balancing with GRE as it will create lot of out of order packets.

Hello Parthiban
Adding these command didnt help
IP MTU 1400
IP Tcp adjust−mss 1300
when you say not to use unequal cost load balancing with GRE
what I need to eleminate from my configuration.
If unequal cost load balancing is an Know Issue then what is the other major reason to move to EIGRP over OSPF

Hi,
What type of load balancing is running on EIGRP.
Is it per packet or per destination?
I have tested GRE over Ipsec with EIGRP ...two 100 MBPS links with per packet load balancing with 0 Drops.

can you share your sample working config.
