Okay, we have in total we'll say 7 sites/locations. Two of these are managed by ourselves and the rest are managed by the ISP. The two that we manage (router 1 and router 2) are connected via a site-to-site/ipsec-l2l (one is an ASA 5510, one is an ASA 5505) and ONE (router 2) of these is also connected to a single ISP router via an additional site-to-site.
All of the ISP routers are connected in a mesh network using MPLS and we don't have any access to these. The local IP scheme in use is 192.168.1-8.xxx we'll say.
Assuming the ISP has their equiptment setup correctly, how will it be possible to make router 1 (and router 2 for that matter) communicate with the rest of the locations? I'm guessing I need to put some type of route in the ASA's like:
route inside 192.168.0.0 255.255.0.0 [isp_wanIP]
Can you even do static routes across a lan to lan VPN?
