How to set static routes for packets, within the same Network?
I have three systems A,B,C. I want to configure A in such a way that all packets from A to C goes via B.
I tried:
1. ip route add 'ip of C' via 'ip of B'
2. route add -net 'net address' netmask gw 'ip of B'
These commands work initially when I try a ping or traceroute and expire after attempting ping twice or thrice.
A's IP Address: 192.168.0.130
B's IP Address: 192.168.0.150
C's IP Address: 192.168.0.140
In Windows systems we achieve routing A's and B's traffic via C by running the following commands in A and C:
route delete 192.168.0.0
route add 192.168.0.0 mask 255.255.255.0 192.168.0.150
After executing the above commands, all network traffic from A and C will be routed via B.
I am looking for a linux equivalent of the same.

tc-route
Route classifier in tc(8) Linux Route classifier in tc(8)
NAME
route - route traffic control filter
SYNOPSIS
tc filter ... route [ from REALM | fromif TAG ] [ to REALM ] [ classid CLASSID ] [ action ACTION_SPEC ]
DESCRIPTION
Match packets based on routing table entries. This filter centers around the possibility to assign a realm to routing table entries. For
any packet to be classified by this filter, a routing table lookup is performed and the returned realm is used to decide on whether the
packet is a match or not.
OPTIONS
action ACTION_SPEC
Apply an action from the generic actions framework on matching packets.
classid CLASSID
Push matching packets into the class identified by CLASSID.
from REALM
fromif TAG
Perform source route lookups. TAG is the name of an interface which must be present on the system at the time of tc invocation.
to REALM
Match if normal (i.e., destination) routing returns the given REALM.
EXAMPLES
Consider the subnet 192.168.2.0/24 being attached to eth0:
ip route add 192.168.2.0/24 dev eth0 realm 2
The following route filter will then match packets from that subnet:
tc filter add ... route from 2 classid 1:2
and pass packets on to class 1:2.
NOTES
Due to implementation details, realm values must be in a range from 0 to 255, inclusive. Alternatively, a verbose name defined in
/etc/iproute2/rt_realms may be given instead.
