ESG ospf area id in IP address form problem

[jorge_luis_hern]

Hi, I'm trying to configure OSPF between an ESG and a Fortigate device, Fortigate use the ospf area id as IP address form, but when I try to configure the ESG with the same area id in IP address form, I can't do that, because the webclient don't allow me to write a dot, even, I try to use REST API but the xml reference says that area id is a number between 0 and a big number, that I don't remember, the NSX documentation says that we can configure ospf id area as a number or in IP address form but I can't.

Any help ??

There are some online videos for integrating a Fortigate with a Cisco router.  It shows that a configuration on a Fortigate of 0.0.0.0 will link up to a Cisco router that is configured for Area 0, due to the fact that OSPF sees the actual value in Hex.  0.0.0.50 would convert to area 50 in NSX; 10.1.1.1 converts to area 167837953.
