SOTM (Satellite On The Move)
This section applies only to those networks with mobile platforms, such as a
maritime environment. VMS 3.6.x incorporates automated features to seam-
lessly handle configuration changes inherent to a mobile environment. If a plat-
form transitions to a new satellite, the VMS will automatically move the
associated antenna, update the Inband Home State, and remove and rewrite the
appropriate routes in the old and new TDM outbounds. QOS rules applying to
the TDM outbound for the remote site will be moved as well. If the transition
involves moving to a different hub, the modems will generate RIPv2 updates to
the edge routers providing a path to the Internet.
This process is illustrated below, in figure 3-54. Configuring this feature
requires that sites are on-line.
