Extended PING

This is similar to what we do in a router if we want to ping a destination IP from a specific source IP that we want.is source ip selfip? if yes, have you tried ping -I option? but if not (selfip), i am not aware of.

e.g.

 external vlan is in 172.28.20.0/24 subnet

root@(ve11a)(cfg-sync Changes Pending)(Active)(/Common)(tmos) list net self 172.28.20.11/24
net self 172.28.20.11/24 {
    address 172.28.20.11/24
    allow-service {
        default
    }
    traffic-group traffic-group-local-only
    vlan external
}
[root@ve11a:Active:Changes Pending] config  tmsh
root@(ve11a)(cfg-sync Changes Pending)(Active)(/Common)(tmos) list net vlan external
net vlan external {
    if-index 112
    interfaces {
        1.1 { }
    }
    tag 4094
}

 ping to external host (172.28.26.70) from specific source ip (200.200.200.11)

[root@ve11a:Active:Changes Pending] config  ping -c 3 -I 200.200.200.11 172.28.26.70
PING 172.28.26.70 (172.28.26.70) from 200.200.200.11 : 56(84) bytes of data.
