Hi Dan, yes I did:

router ospf 100
 router-id 1.1.1.1
 log-adjacency-changes
 redistribute isis level-1-2 metric 20 subnets tag 115
 network 10.8.0.0 0.0.255.255 area 0
 network 200.0.0.0 0.255.255.255 area 0
!
router isis
 net 47.0001.1111.1111.1111.00
 redistribute connected metric 1 metric-type external level-1-2
 redistribute ospf 100 metric 3 level-1-2

BUT OSPF does not get the connected route, only the loopback on R3

R1#sh ip ospf data ext self

            OSPF Router with ID (1.1.1.1) (Process ID 100)

                Type-5 AS External Link States

  LS age: 696
  Options: (No TOS-capability, DC)
  LS Type: AS External Link
  Link State ID: 200.3.3.0 (External Network Number )
  Advertising Router: 1.1.1.1
  LS Seq Number: 80000002
  Checksum: 0x6EEA
  Length: 36
  Network Mask: /24
        Metric Type: 2 (Larger than any link state path)
        TOS: 0
        Metric: 20
        Forward Address: 0.0.0.0
        External Route Tag: 115

Hello Pierre,

Probably a silly question, but did you give it a metric when redistributing
connected into ISIS?
