Chapter 26 Configuring BME Multicasting
BME Operation
Connection Management Criteria
The following are the toot connections and leaf connections that can be added in any order:
•
Add root first and then leaves.
•
Add leaves first and then root.
•
Add root in between adding leaves.
Root and leaf connections can be deleted in any order.
Root can be deleted and replaced with a new root.
Connection Management with Cisco WAN Manager
Cisco WAN Manager management includes the following functions:
•
Connection filtering by multicast type (root/leaf)
• Multicast connection addition, deletion, and modification
•
Multicast view of multicast group of a selected connection
• No multicast specific statistics support
•
No service MIB support
BME Operation
Cables are connected between port 1 and port 2 of the back card, transmit to receive and receive to
transmit.
Note
Removing the physical loopback cables or placing line 1 or 2 into loopback will prevent the cells
from the root reaching the leaves.
BME Cell Replication
Figure 26-1 shows a BME with a single root input multicasting with 3 leaves. The root connection can
be added at a BPX switch (BPX switch A) distant from where the traffic is replicated by the BME card
(BPX switch F) and routed through a number of BPX nodes. Similarly, the leaves can be routed from the
multicasting node through a number of nodes before reaching their destination.
