Here's a scenario, both router A and B are connected via an MPLS cloud. both routers and MPLS communicate with one another via RIP. I've configured GRE tunnel between router A and B and pass EIGRP over this tunnel. Here is the problem:
- ALL applications (telnet, citrix, dns etc) are running fine except for Outlook when connecting to an Active Directory MS Exchange server.
When I turn off the GRE tunnel (hence EIGRP also), Outlook will start working again.
Thanks for your reply. The suggestion works flawlessly. I did try another (longer) solution and my one also works. It's to do with turning off the DF bit which was generated by MS Exchange2K3 (but not by Exchange 5.5). I created an ip extended ACL (101) that matches both the source and destination IP subnets, create a route map with a match statement pointing to the ACL and do a set ip df to 0.
