Re: Router-on-a stick Cisco Router with Juniper Switch

That does make sense. Though, I did add VLAN 1 to the member list of ge-0/0/30 and that didn't make a difference.

If this is true with lldp, why can Juniper6 and ASR2 see eachother on the ge-1/0/34 gig0/0/5 link while VLAN 1 is not allowed? As you can see in my original post, the native vlan is the same for both links. This just adds in more questions. Here is the detailed lldp neighbor output from he ASR2 side:
