Spoke to Spoke VPN via Hub

All,

Please find attached the diagram and HUB /SPOKE configs I am using to get spoke to spoke communication via the VPN hub.

The VPN is functioning correctly between the hub and spokes just not between the 2 spokes! please help!

Re: Spoke to Spoke VPN via Hub

Hi,

This is a common problem. The router in the hub will discard the traffic since a packet cannot exit the same interface it entered.

Try the following commands on the hub outside interface:

no ip route-cache

no ip route-cache cef

no ip route-cache flow

If this doesn't work, you might need to implemetna a GRE/IPSEC implementation, with the hub having one GRE interface for each spoke.

Please rate if this helped.

Regards,

Daniel
