Por las dudas en linux el parámetro para ping es -I
-I interface
interface is either an address, an interface name or a VRF name. If interface is
an address, it sets source address to specified interface address. If interface is
an interface name, it sets source interface to specified interface. If interface
is a VRF name, each packet is routed using the corresponding routing table; in
this case, the -I option can be repeated to specify a source address. NOTE: For
IPv6, when doing ping to a link-local scope address, link specification (by the
'%'-notation in destination, or by this option) can be used but it is no longer
required.
