For my ansible tests to work, I need to add the following route on my sonic-host dut in order to reach my PTF docker on the ansible hosts:

sudo ip route add 10.250.0.0/24 via 152.148.146.161 dev eth0 src 152.148.151.159

However, the "152.148.146.161" mentioned above is not a generic/default lab gateway but the mgmt ip of my ansible host.

admin@sonicHost:~$ sudo ifconfig eth0
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 152.148.151.159  netmask 255.255.248.0  broadcast 0.0.0.0
<snip>

admin@sonicHost:~$ ip route
default via 152.148.144.1 dev eth0 proto 196 metric 20 

I see there's a way we can add routes in group_vars/lab/lab.yml using the variable forced_mgmt_routes but I don't see an option of adding the gateway in templates/minigraph_meta.j2. The example https://github.com/Azure/SONiC/wiki/Configuration is not using the minigraph format either.

In other words, in the example above, I do not want to use the default GW of 152.148.144.1 for the 10.250.0.0/24 subnet.

So is there a way to specify the route and next-hop in a custom manner?

Thanks.
