Round Trip Time Mpls Vpn Monitor Control Lpd

1.3.6.1.4.1.9.9.42.1.2.15.1.15

When set to true, this implies that LPD (LSP Path Discovery) is enabled for this row. The Auto SAA L3 MPLS VPN will find all the paths to each of the PE's and configure RTT operation with rttMonCtrlAdminRttType value as 'lspGroup'. The 'lspGroup' probe will walk through the list of set of information that uniquely identifies a path and send the LSP echo requests across them. All these LSP echo requests sent for 1st path, 2nd path etc. can be thought of as 'single probes' sent as a part of 'lspGroup'. These single probes will of type 'rttMplsVpnMonCtrlRttType'. 'lspGroup' probe is a superset of individual probes that will test multiple paths. For example Suppose there are 10 paths to the target. One 'lspGroup' probe will be created which will store all the information related to uniquely identify the 10 paths. When the 'lspGroup' probe will run it will sweep through the set of information for 1st path, 2nd path, 3rd path and so on till it has tested all the paths.
