Hi All,
I have found the issue about routing entry of remote vpn session on ASA 5516.
Below is a routing entry that it is stuck in routing table.
I checked the vpn-sessiondb and didn't see it up.
It happens sometimes with some assigned IPs not all.
Even clearing vpn session it is still there. And ASA has OSPF running, this routing entry is active to other OSPF neighbor.
V 10.225.20.250 255.255.255.255
connected by VPN (advertised), outside
#sh vpn-sessiondb ra-ikev1-ipsec filter a-ipaddress 10.225.20.250
INFO: There are presently no active sessions of the type specified

And here is the configuration of the remote vpn.
