Depending on your configuration, it's possible. There's certainly nothing about the ACL that would explicitly deny it.<br />

Is the deny-ospf-out acl doing anything? I don't see it being applied to any interface or referenced anywhere else. <br />

Is it safe to assume that we are advertising OSPF out to everyone?<br />

Advertising OSPF and security

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
