I have three Cisco routers (1 x 1841 2 x 877) running ina DMVPN / Multipoint tunnel config as suggested in the Cisco text http://www.cisco.com/en/US/tech/tk583/tk372/technologies_configuration_example09186a008019d6f7.shtml
The Tunnels are up, and I have no problems pinging to either side (my Internal addresses are 172.16.0.1/24 for the master and 172.16.0.2-3/24 for the branch offices).
I have configured OSPF on the router at our head office and ahve been able to peer both 877's in hte brances using ospf as well. I am using Area 0 for all the Head office subnets and Areas 2+3 for the branches.
On the surface everything looks really good, however at random intravals when viewing a "debug ip ospf adj", I see the error OSPF: Cannot see ourself in hello from 18.104.22.168 on Tunnel1, state INIT
this causes the routers to regnotiate their ospf relationship which is causing all sorts of problems because for a few moments my routing tables are missing the learned routes.
Can anyone shed any light on this error?
