Intra-Cluster VNFC Communication Through Packet Ports

Overview

The SBC supports IP addresses (IPv4 and IPv6) for packet interface (pkt0 and pkt1) for intra-cluster Virtual Network Function Component (VNFC) communication of Distributed SBCs (D-SBCs) by assigning an IP Interface Group. Packet interface along with management interface can be used for intra-cluster VNFC communication.

The SBC uses UDP port number 3057 associated with the management interface for intra-cluster VNFC communication. When packet interface is used for intra-cluster VNFC communication, set the parameter baseUdpPort to a value higher than 3057.

The meta variable names are used to retrieve IP addresses for intra-cluster VNFC communication. For example, on a cloud Media-SBC (M-SBC), the IPv6 address of pkt1 is IF3.IPV6, and the IPv4 address of mgt0 is IF0.IPV4.

Configuration Example

To configure packet interface using IPv6 address for VNFC communication in a Cloud M-SBC cluster:

set system clusterAdmin clusterComm type ip addressContext default ipInterfaceGroup MLIG2 pktIpVar IF3.IPV6
commit

To configure packet interface using IPv4 address for VNFC communication in a Cloud M-SBC cluster:

set system clusterAdmin clusterComm type ip addressContext default ipInterfaceGroup MLIG2 pktIpVar IF3.IPV4
commit

To configure management interface using IPv6 address for VNFC communication in a Cloud M-SBC cluster:

set system clusterAdmin clusterComm type mgmt mgmtInterfaceGroup mgmtGroup mgmtIpVar IFO.IPV6
commit

To configure management interface using IPv4 address for VNFC communication in a Cloud M-SBC cluster:

set system clusterAdmin clusterComm type mgmt mgmtInterfaceGroup mgmtGroup mgmtIpVar IFO.IPV4
commit
