Need Help with Userman and OSPF

HI,

I would like some help with userman and src nating the traffic out as the OSPF loopback IP as its currently sending traffic out as the interface IP for that link resulting in the external router within the OSPF area rejecting the traffic and timing out on the other router i can see the traffic using the IP 100.64.0.193 and i have tried that src nat rule to manipulate it and works fine for ICMP traffic but does not help userman

/interface bridge
add name=OSPF-Loopback
/routing id
add disabled=no id=10.1.1.13 name=10.1.1.13 select-dynamic-id=""
add address=10.1.1.13 interface=OSPF-Loopback network=10.1.1.13
add address=100.64.0.193/30 interface="AK-DR-02" network=\
    100.64.0.192
/ip firewall nat
