Configuring Optional Characteristics

pathEcho—Finds a path to the destination and echoes each device in the path;
corresponds to SNMP traceroute
You must specify this value before any other.
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"
on page 67.)
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.
Example
host1(config-rtr)#type echo protocol ipIcmpEcho 10.10.0.9
Use the no version to remove the type configured for the probe.
See type
In addition to configuring the probe's type, you can configure the probe characteristics
presented in Table 7 on page 64.
