Interoperating with
Cisco Backbone
Figure 2-15 is an example of LANView interoperating with a Cisco backbone. The
key difference in this application is that even though RFC877 is used as the
interoperability encapsulation between the routers and other RFC877-compliant
routers, connectivity between the routers uses the CODEX encapsulation. This
demonstrates support for multiple encapsulations within the same LANView.
