BME Multicasting 10-3
Connection Management Criteria
BME Restrictions
• BMEs can function in the following two BPX node configurations:
— BCC-4s and BXMs only
— BCC-3 control cards and legacy cards only, including BNIs and ASIs
• VC frame merge is not currently supported
Address Criteria
• The VPI of a multicast connection indicates the multicast group to which it belong.
• The VPI.VCI assigned to a multicast connection is unique for that card.
• If the VCI = 0 for a multicast connection, this indicates a root connection.
• If the VCI is not = 0 for a multicast connection, this indicates a leaf connection.
• If the root connection of a given multicast group is added to port 1 of the two port card, then the
leaves belonging to that multicast group must be added to port 2, and vice versa.
For example, if 12.1.50.0 is added on port 1, then the leaves should be 12.2.50.50, 12.2.50.100,
12.2.50.101 etc. Similarly, if a root 12.2.60.0 is added on port 2, then the leaves should be
12.1.60.101, 12.1.60.175, etc.
Connection Management Criteria
Root connections and leaf connections 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 StrataView Plus
• Cisco StrataView Plus 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
