JJ in the Sunday Warm-up

[Bonified]

400-800/50, I have just under 22K. I have been extremely active in the last couple of rounds, shoving for 10K in the SB, reraising allin with 77, reraising allin with KK and raising with AK (all uncontested).

Next hand immediately following AK I pick up JJ in 3rd spot (so 6 players to act) and make it 2100. SB, who has also been active and who folded when I reraised him with 77, makes it 6400 (he has me covered). His OPR stats are pretty good, average stake $250 and winning $45K in the last 4 months. What's your line here ?

I call, flop comes 872 rainbow and he shoves which gives me almost exactly 2-1 odds to call all-in. Now what ?

Apologies if this is standard (it might not be too hard) but I would value any input.
