Hello
A few things look incorrect
Your crypto map peers are incorrect, your interesting traffic ACL doesn't reflect RTR1 & RTR2 lan networks and you do not have any specific route to each others lan subnet
Try the following:
RTR1
crypto map CMAP 10 ipsec-isakmp
no set peer 192.168.1.2
set peer 172.16.1.2
ip access-list extended VPN-TRAFFIC
no permit ip 168.254.1.0 0.0.0.255 20.20.10.0 0.0.0.255
permit ip 168.254.1.0 0.0.0.255 172.168.1.0 0.0.0.255
ip route 172.168.1.0 0.0.0.255 172.16.1.2
RTR2
crypto map CMAP 10 ipsec-isakmp
no set peer 192.168.1.2
set peer 172.16.1.1
ip access-list extended VPN-TRAFFIC
no permit ip 20.20.10.0 0.0.0.255 168.254.1.0 0.0.0.255
permit ip 172.168.1 0.0.0.255 168.254.1.0 0.0.0.255
ip route 168.254.1.0 255.255.255.0 172.16.1.1
