PE to Unmanaged CE Pings remote ping group

The PE to Unmanaged CE Pings default remote ping group is used by MPLS Manager to generate all possible PE-to-remote-Unmanaged-CE pings in a VPN, and to monitor and analyze the ping test results to determine PE-to-Unmanaged-CE reachability. It has a single, valid setting named PE to Unmanaged CE Ping Settings.

This setting determines (1) the creation of remote ping entries in the SNMP Ping MIB tables on the source PEs and (2) the polling intervals that are used by MPLS Manager to monitor the ping test results. MPLS Manager monitors the ping test results by probing the Ping MIB tables on the source PEs.

By default, each PE in a VPN pings every local and remote Unmanaged CE or multi-VRF CE in the VPN. A remote Unmanaged CE is an Unmanaged CE that is attached to a peer PE.

Note:

The term Unmanaged CE, as used here, refers to a CE that is neither in the repository of the MPLS Manager nor in the repository of the source IP Availability Manager.

PE to Unmanaged CE Ping Settings parameters and their values lists the PE to Unmanaged CE Ping Settings parameters.

Table 1. PE to Unmanaged CE Ping Settings parameters and their values

Parameter	Values	Description
AnalysisMode	ENABLED,DISABLED Default: DISABLED	Enables or disables the MPLS Manager triggering of PE-to-Unmanaged-CE pings and the subsequent polling and analysis of the polled ping test results.
DestinationIP	Regular expression Default: *.*.*.* (By default, all VRF-associated interface IP addresses on a destination Unmanaged CE are selected; that is, all CE interface IP addresses associated with VRF interface IP addresses on a peer PE are selected.)	Specifies the wildcard expression to use to select the VRF-associated IP addresses on the destination Unmanaged CEs for PE-to-Unmanaged-CE pings. An example entry is 163.*.*.*, which would limit the selected VRF-associated IP addresses to just those beginning with 163.
DestinationName	Regular expression Default: * (By default, all Unmanaged CEs are selected as destination Unmanaged CEs.)	Specifies the wildcard expression to use to select the destination Unmanaged CEs for PE-to-Unmanaged-CE pings. An example entry is C*, which would limit the selected destination Unmanaged CEs to just those that have names beginning with C.
PacketSize	0 to 65507 octets Default: 100 octets	Specifies the size of the IP packet to be transmitted in a ping request executed by the source PE.
PingTimeout	1000 to 60000 milliseconds Default: 2000 milliseconds	Sets the amount of time for a source PE to wait for a ping response before the ping request times out.
PollingInterval	30 to 3600 seconds Default: 240 seconds	Sets the time between successive polls to retrieve the ping test results from the source PE.
PollingTimeout	2000 to 10000 milliseconds Default: 2000 milliseconds	Sets the amount of time to wait for a poll response before trying again to retrieve the ping test results from the source PE.
Retries	0 to 10 retries Default: 2	Sets the number of retry polls to perform when the initial poll fails.
SourceName	Regular expression Default: * (By default, all PEs are selected as source PEs.)	Specifies the wildcard expression to use to select the source PEs for PE-to-Unmanaged-CE pings. An example entry is A*, which would limit the selected source PEs to just those that have names beginning with A.
USR_Destination-InterfaceDesc	Regular expression? “glob()” patternDefault: *	Specifies the pattern of description of destination PE interfaces for which "PE to Unmanaged CE" remote pings are generated.
USR_UnmeshFlag	TRUEFALSEDefault: FALSE	If the flag is true, only “PE to local unmanaged CE” pings are generated. If the flag is false, both "PE to local unmanaged CE" and "PE to remote unmanaged CE" pings are generated.

For each PE-to-Unmanaged-CE remote ping group configured by an administrator, MPLS Manager writes the ping entry to the source PE and periodically refreshes the ping entry in accordance to the “Refresh/calculation interval” on page 152, so that it does not expire until the administrator deliberately disables it.

Each configured PE-to-Unmanaged-CE remote ping group is represented by MPLS Manager as a RemotePing object. The MPLS Management Suite User Guide describes the RemotePing object.
