Linux : ping /traceroute to destination strange output.

In our linux server we there are 2-bond interface has been configured.

server IP = 10.X.X.X
bond-0 = 192.X.X.X

when we try to ping destination server IP, it was not reachable.
when we traceroute/ping request to target server , the output getting like below
#from 192.X.X.X icmp_seq=54 destination host UNreachable

very strange to get this kind of output.

Source should be Server IP, where as it giving us reply Bond-0, This had some partial impact some service.
Kindly advise how to resolve this issue.

the port which we had opened in firewall between SOURCE SERVER IP - DESTINATION SERVER IP

that have been working since long time.

when we tracerout as it is giving reply from bond-0 interface, that firewall rules setting not configured .. so was the issue I suspect.

if it gives reply from server IP, my is is it will resolve the issue of the services which has been running on the server.

Kindly advice how to fix from OS side, rather Network.

Look at the routing table: netstat -rn
Ifconfig -a

@arnold
could pleas provide solution to work .. I can see output for netstat -an

arnold

-an reports connections I asked for -rn which reports the routing table. This dictates how your ping, traceroute works
ifconfig -a
Reports the network adapter line up.

Please note 192.168 and 10. Are part of a private ip range and is not unique to you where you need to mask it.

If you can, include the traceroute output.
