When I set a complete strict path from Juniper everything works fine. Once I 
remove all hops from the path list (i.e now Juniper sends a Path w/o ERO) 
Cisco rejects it. All routes are available in route table.

Code is 24/5 in path error (no route to destination).

Cisco version is 12.0.21 (ST)

7w0d: RSVP 10.20.1.101_1-10.20.1.6_17: PATH message for
10.20.1.6(FastEthernet4/5) from 10.10.29.101
7w0d: RSVP 10.20.1.101_1-10.20.1.6_17: PATH message with no ERO; no path
meets constraints
7w0d: RSVP session 10.20.1.6_17: send path error to 10.10.29.101 about
10.20.1.6
7w0d: RSVP session 10.20.1.6_0: IP to 10.10.29.101 length=132 checksum=4DC6
TOS=0x0  (FastEthernet4/5)

Thanks,
