A.1.2 H OME / BRANCH O FFICE D ESIGNATION
For each Router WAN link, one site is designated the home office and the other site is designated the
branch office. The home office is usually a central site that may be attached to the Internet, and to
connecting branch offices.
When a remote site is designated as a branch of fice (with IP routing enabled), a default route for the
modem interface is added. When the remote router doesn’t know how to reach an address, it sends the
traffic for that address to the home office, using the default route.
