8.14.3 Example for configuring frame relay switching routes
Networking requirements
You can implement the FR switching route function in a network with two or more routers. As
shown in
Figure 8-7, Router B and Router C can be considered as routers for FR switching,
enabling the serial 1/0/0 on Router A and Serial 2/0/0 on Router D to interconnect with each
other through the FR switching of Router B and Router C.
