OSPF Configuration for 2 sites

I have site A- Main site and Site B secondary site. 

Site A- MX100 and MS350 48fp

Site B- MX100 and MS350 48fp

 

How do I setup OSPF to advertise routes between sites? Should site A be area 0 and site B area 1?

Kind of a big deal

Check out these two links. They should help with this.

 

For OSPF, in what you describe you would just make both part of Area 0. Area boundaries are on layer 3 devices, not between layer 3 devices. You can get a pretty big number of routers in an area without having to worry about areas.

Re: OSPF Configuration for 2 sites

You won't be able to use OSPF between the sites - you should not need it.

 

In each case, the default route for each switch should point to its local MX.  The MX will need to know the routes in use at each site already, and you simply include those in AutoVPN.
