Upon importing router and switch topology from IP Availability Manager, MPLS Manager performs its own discovery on the router and switch devices to gather MPLS, VPN, and BGP topology information. It models this information as logical MPLS, VPN, and BGP topology objects in its repository, and maps that topology to the underlying physical-transport topology that is discovered by IP Availability Manager.
MPLS Manager monitors the availability of the MPLS and VPN objects in its repository by:
-
Subscribing to certain device, chassis, card, interface, and network-connection status updates from IP Availability Manager.
-
Monitoring the status of the MPLS and VPN objects through:
-
SNMP polling.
-
Periodic remote pinging.
Users can also invoke on-demand remote pings and on-demand LSP pings to manually monitor routing-protocol and LSP connectivity in the managed MPLS network.
MPLS Manager monitors the availability of the BGP objects in its repository by connecting to an VMware Smart Assurance Network Protocol Manager for BGP and subscribing to certain BGP status updates. The Network Protocol Manager for BGP is included in an MPLS Manager deployment only if MPLS-BGP cross-domain correlation is enabled.
