Can I use lt-0/0/0 interface to connect two bridge domains?
yes You can but You are missing this line:
set chassis fpc 0 pic 0 tunnel-services bandwidth 1g
I tried to use lt-0/0/0 interface. Can I do this ?
I don't have experience with "EVE" but regular (v)MX suppots LT interfaces just fine - see above for necessary command line.
And some more comments:
1/ You are basically creating one big bridge domain/BD with this interconnect so what's the point here? You could create a single BD with all Ethernet interfaces mentioned and live happily ever after. I never use such BD interconnect in my designs, and never had to
2/ If You are still insisting on this LT interconnect, then aligh VLAN-ids on both sides of LT interface pair. If You are worried about 802.1Q tags, then JUNOS BD has VLAN normalization enabled by default, so Your VLAN tags will get rewritten on entry to each BD automatically.
