Chapter 25 Configuring BXM Virtual Trunks
• A virtual trunk is added between port 3 on the BXM and port 2 on the UXM (see Figure 25-6).
Given this situation, you would perform these steps:
Initial Setup
1.
In the public
2.
ATM cloud
At BPX_A
3.
4. At BPX_A
5. At BPX_A
6. At BPX_B
At BPX_B
7.
8. At BPX_B
9. At IGX_A
At IGX_A
10.
At IGX_A
11.
12. At BPX_A
13. At BPX_B
The VPI values you choose by using cnftrk must match those used by the cloud VPC.
In addition, both ends of the virtual trunk must match with respect to:
• Transmit Rate
VPC type
•

Example: Virtual Trunk Across an ATM Network
Contact Customer Service to enable virtual trunking
on the nodes in your network.
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.
Up virtual trunks 4.3.1 and 4.3.2 on BXM port 4.3.
Configure the virtual trunks to match the cloud's VPC
configuration, including: VPI, header type (UNI or
NNI), traffic classes, and VPC type, and so on.
Configure the number of conids, bandwidth, and so on,
available for the virtual trunks.
Up virtual trunks 5.1.1 and 5.1.2 on BXM port 5.1.
Configure the virtual trunks to match the cloud's VPC
configuration, including: VPI, header type (UNI or
NNI), traffic classes, and VPC type, and so on.
Configure the number of conids, bandwidth, and so
on., available for the virtual trunks.
Up virtual trunks 10.2.1 and 10.2.3 on IGX trunk port
10.2.
Configure the virtual trunks to match the cloud's VPC
configuration, including: VPI, header type (UNI or
NNI), traffic classes, and VPC type, and so on.
Configure the number of conids, bandwidth, and so on,
available for the virtual trunk.
Add the virtual trunks between three nodes. Using
addtrk 10.2.1 ... at IGX_A and addtrk 5.1.1 ... at
BPX_B would also add the virtual trunks.
Add the virtual trunks between the two nodes. Using
addtrk 10.2.3 ... at IGX_A would also add the virtual
trunks.
