Example: Virtual Trunk Across an ATM Network
The procedure in this section gives the specific commands for every step in adding one virtual trunk
across an ATM network. This is a very typical situation.
This procedures assumes this hypothetical situation:
• On one side of the cloud is a BPX with a BXM trunk card in slot 4.
• On the other side of the cloud is an IGX with a UXM trunk card in slot 10.
• A virtual trunk is added between port 3 on the BXM and port 2 on the UXM (see Figure 24-6).
Given this situation, you would perform these steps:
1. Initial Setup Contact Customer Service to enable virtual trunking
on the nodes in your network.
2. In the public
ATM clou d
Obtain the VPCs for the virtual trunks for the service
provider. These are the VPCs that are configured
within the ATM cloud by the service provider to
support the virtual trunks.
