I’ve been battling with getting Windows RRAS ospf and Cisco ios ospf to become neighbours for the past few days.

If you turn on ospf debug in windows and the following shows up :

Rejected an OSPF packet from x.x.x.x to 224.0.0.5 because the OSPF data length in the OSPF header was 48 but the length calculated from the IP Header fields was 60.

You should disable the following on the cisco ios:

router ospf 100

no capability lls

Also, if you are running ISA with RRAS you should disable  “block fragmentation”
