Hey ras, thanks for your reply :) The show route commands look pretty normal to me (I've pasted output below), the direct/local routes pertinent to the 10.10.255.192/30 subnet are there. I was running JUNOS 9.0R2 earlier when I first posted this message, but upgraded it just now to 9.1R1.8. Unfortunately the problem persists :-(
FWIW, on the Cisco side, I have it connected to a GLC-T SFP (for copper gig-e). Thinking that it may be a bad sfp or line card at Cisco side, I configured a 2nd interface (ge-0/0/2.0 on the EX) headed out to a different, second Cat6500 unit. But it's exhibiting exact same problem on that 2nd interface as well (routes installed, link is up/up, negotiated as 1000BaseT but unable to ping across; getting sendto: Network is down message at EX end). In the meantime, I'm going to go ahead and open a JTAC case and also try setting it up as a layer-2 access port with an L3 vlan on top of it to see if it does anything different..
