Hello!
In a man page for ping(8) and in it's help output I found option "-e":
-e gateway
Specifies to use gateway as the next hop to the destination.
The
gateway must be a neighbor of the sending node.
I tried to use this argument, ping ignores this parameter and sends the
packet via default gateway.
For example I have a tun0 which has ipv6 default gw, and an established
bridge0 which has available some LL addresses:
Neighbor Linklayer Address Netif Expire S
Flags
fe80::2a0:98ff:fe1d:e270%bridge0 00:a0:98:1d:e2:70 bridge0 23h56m34s S R
I tried to run:
ping -6 -e FE80::2A0:98FF:FE1D:E270%bridge0 google.com
But the packet was sent via tun0 interface.
What is wrong with it?
