How to do routing on IPsec Site-to-Site tunnel

I have successfully established IPsec Site-to-Site tunnel from OpenWRT to VYOS. Can anyone tell me how to do routing on tunnel.
Here is the output of ipsec statusall command.

What routing do you want to do? If you ping from a host in towards another host in, won't it reply back?

Are you thinking of a Route-based VPN?

yes i want route based vpn

not getting reply back
