Standalone System
You can connect a standalone system to a system that already has a PE to make it dual homed. In the
following illustration, PE 1 is connected to System A and System B is a standalone.
Figure 108. Standalone System and System with PE — Before setting up Dual Homing
To convert the above system into a dual homing setup, perform the following:
1 Repeat the steps 1 to 6 from
2 Change the uplink port connections of the PE, so that the uplink ports are connected to each of the VLT
peers. In the above example, the link connected to Te 0/1 in System A is disconnected and connected to
Te 1/4 in System B.
3 Remove the disconnected interface (Te 0/1) from the configuration mode of PE 1 in System A. The
configuration would be already available in System A and needs to be removed.
