Chapter 25 Configuring BXM Virtual Trunks
How Virtual Trunking Works
Figure 25-3 BXM Egress VIrtual Interfaces and Qbins
AutoRoute connections use qbins 0 through 9.
Virtual Switch Interfaces (VSIs), which support master controllers use qbins 10 through 15, as
applicable. The BXM can concurrently support MPLS and AutoRoute, or PNNI and AutoRoute, or
MPLS and PNNI at the same time on a given VSI.
Virtual Trunks Across a Public ATM Cloud
An example of a number of virtual trunks configured across a Public ATM Network is shown in
Figure 25-4. There are three virtual trunks shown across the network, each with its own unique VPC.
The three virtual trunks shown in the network are:
•
between BPX_A 4.3.1 and IGX 10.2.1
•
between BPX_A 4.3.2 and BPX_B 5.1.1
•
between BPX_B 5.1.2 and IGX_A 10.2.3
Each VPC defines a virtual trunk that supports the traffic types shown in Table 25-2.
