This is in unix environment. I have multiple routes in a host (visible with 'ip route show' command). If I am pinging an address, how can I find out which gateway was used to route the tracffic?
I tried using traceroute command, but it does not show the immediate gateway.
From below output, 10.58.227.1 is my default gateway.
# ip r l 10.58.227.0/24 dev front_eth1 proto kernel scope link src 10.58.227.231 169.254.0.0/17 dev bond0 proto kernel scope link src 169.254.0.4 default via 10.58.227.1 dev front_eth1 proto gated
When I do traceroute to an external address, the gateway used (default gateway 10.58.227.1) is not shown in output.
# traceroute -n -I 10.63.21.118 traceroute to 10.63.21.118 (10.63.21.118), 30 hops max, 40 byte packets 1 10.58.112.1 0.507 ms 1.008 ms 1.017 ms 2 10.63.21.118 0.228 ms 0.233 ms 0.234 ms
Is there any option to view the same information as given by traceroute command, including the gateway used for routing?
