You can configure the probe type—either an echo probe or a path echo probe after entering into the RTR Configuration mode.
You must specify the probe type value before any other RTR probe configuration. If you change the type for an existing RTR entry, all values are reset, including the administrative status. There is no default value. More than one RTR entry can become active, provided each entry’s target address is unique.
If you configure multiple RTR entries to use the same target address, you must issue the receive-interface command to specify the interface on which the RTR probe expects to receive responses. (For information, see Setting the Receiving Interface for the RTR Entry.)
If you use a target address already configured for another RTR entry that is active, the test will not run if both entries are in the same virtual router. If they are in distinct virtual routers, however, there is no restriction.
To enter into the RTR configuration mode:
Use the no version to delete all configuration information for an RTR probe.
To configure the probe type:
Use the no version to remove the type configured for the probe.
