2820Vn LAN-LAN routing issues was created by 1tsolutions
We have a couple of 2820Vn routers at two sites in the UK (we'll call these sites A and B).
One UK site (Site A) dials the other UK site (Site B) over PPTP fine.
Both UK sites (A and B) dial over IPsec to a Sonicwall in the US with no problems.
The routing table generated on the 2820s is a bit hit-and-miss. Sometimes, the 2820s generate circular routes trying to reach the network at Site C in the US.
This appears to depend on the order the VPNs were started.
Is there any way of configuring the VPNs with static routes so the circular routes aren't generated?
Thanks,
- Andrew

Try setting the RIP Direction to disabled in all the VPN profiles and then reboot both routers to clear the routing table. It may be RIP communication between the router routers is causing the loop.
