I have configured a static route in my router to point to a directly connected Juniper at 10.100.100.1. The full command is:
ip route 172.21.18.0 255.255.255.192 10.100.100.1
The interfaces on my router are as follows:
Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 10.100.100.2 YES NVRAM up up
FastEthernet0/1 172.26.10.57 YES NVRAM up up
FastEthernet0/1/0 192.168.50.1 YES NVRAM up up
Now when I do a traceroute to 172.21.18.10 this is what I am getting, does anyone know what I am facing here?

Type escape sequence to abort.

You have a loop. Can you post the configs from both Juniper and Cisco?
What is your topology looks like?
Also, do you have default route on the Cisco?

Yes I have a default router that points out that same direction. However if I try to go to any publicly routable IP then the default route kicks in and sends it but if I try to go to a private IP range that would only match the default route then I get the same result as above. So basically only the 10.0.0.0, 172.16-32, are causing the loop. The 192.168 goes out BGP.
I can get the config of the Cisco but we dont have access to the Juniper it is Customer equipment
