The PE to VRF Pings default remote ping group is used by MPLS Manager to generate all possible PE-to-remote-VRF pings in a VPN, and to monitor and analyze the ping test results to determine PE-to-VRF reachability. It has a single, valid setting named PE to VRF 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 remote VRF in the VPN. A remote VRF is a VRF hosted by a peer PE. A remote VRF may also be a VRF hosted by a multi-VRF CE that is part of the VPN.
PE to VRF Ping Settings parameters and their values lists the PE to VRF Ping Settings parameters.
| Parameter |
Values |
Description |
|---|---|---|
| AnalysisMode |
ENABLED,DISABLED Default: DISABLED |
Enables or disables the MPLS Manager triggering of PE-to-VRF pings and the subsequent polling and analysis of the polled ping test results. |
| DestinationIP |
Regular expression Default: *.*.*.* (By default, all interface IP addresses associated with the destination VRF are selected.) |
Specifies the wildcard expression to use to select the interface IP addresses associated with the destination VRFs for PE-to-VRF pings. An example entry is 163.*.*.*, which would limit the selected interface IP addresses to just those beginning with 163. |
| DestinationName |
Regular expression Default: * (By default, all destination VRFs are selected.) |
Specifies the wildcard expression to use to select the destination VRFs for PE-to-VRF pings. An example entry is C*, which would limit the selected destination VRFs 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-VRF pings. An example entry is A*, which would limit the selected source PEs to just those that have names beginning with A. |
For each PE-to-VRF 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-VRF remote ping group is represented by MPLS Manager as a RemotePing object. The MPLS Management Suite User Guide describes the RemotePing object.
