Router-on-a stick Cisco Router with Juniper Switch

I am having trouble getting IP connectivity between two Cisco ASR routers connected to a pair of Juniper EX4500-40f switches in a virtual-chassis setup. The Juniper switch is the new element here, as a similar setup has worked connected to different vendor's switches.

 

I have included all of the configuration details here, I've been racking my brain over this all weekend and can't figure out what is wrong. No pings between any of the addresses work.

 

ASR1 Gig0/0/5 (10.10.100.1) is connected to Juniper6 ge-0/0/30

ASR2 Gig0/0/5 (10.10.100.2) is connected to Juniper6 ge-1/0/34

 

Transceiver types are the same on both sides for both links (1Gb SX). Media is correct.

    }

                             VLAN100             100   tagged   unblocked

 

I also have an IP address for VLAN 100 configured on Juniper6

 

    VLAN100 {
        vlan-id 100;
        l3-interface vlan.0;
    }

 

    vlan {
        unit 0 {
            family inet {
                address 10.10.100.3/24;
            }
        }
    }

 

Any help would be appreciated.
