Description: Defines ZTE ZXROSNG L2/L3 VPN bridge configuration for integrated Layer 2 and Layer 3 VPN service delivery.
Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
What Is ZXROSNG-L2L3VPN-BRIDGE-MIB?
This is a ZTE-specific MIB for the ZXROSNG (ZXR10 next-generation OS) platform, covering integrated Layer 2/Layer 3 VPN bridge configuration, allowing a single service instance to combine bridged (L2VPN) and routed (L3VPN) forwarding. It exposes configuration objects for defining these bridge instances, their associated interfaces, and the VPN service parameters that tie them together. Its monitoring value is primarily service configuration verification: administrators confirm that a bridge instance is correctly provisioned with the intended L2 and L3 attachment circuits, which helps diagnose why a VPN customer is experiencing connectivity loss between bridged and routed segments of their service. It depends on underlying MPLS/VPN infrastructure and standard bridge MIBs, since this module coordinates between them rather than replacing their functions. It is typically deployed by service provider engineers provisioning combined L2/L3 VPN services on ZXROSNG-based ZTE routers, relying on ZXROSNG-L2L3VPN-BRIDGE-MIB SNMP monitoring to confirm each bridge instance's attachment circuits match the intended service design.
IPNetwork Monitor allows you to monitor SNMP objects defined in ZXROSNG-L2L3VPN-BRIDGE-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- ZTE ZXROSNG-based router
Monitoring Examples
An engineer checks a bridge instance's configuration to confirm which physical or logical interfaces are bound to it as L2 attachment circuits versus which are routed into the L3VPN, verifying the mapping matches the customer's service design. If traffic fails to pass between the bridged and routed portions of a hybrid VPN service, this configuration table is the first place to check for a missing or mismatched interface binding. No sample objects were present in the source extract, so exact object names cannot be confirmed here.
What Can Be Monitored
- bridge instance configuration
- L2 attachment circuit binding
- L3VPN interface binding
- VPN service parameters
