SQL & PL/SQL :: Ranking Based On A Group?

I have a table t

CREATE TABLE T
(ID NUMBER(4),
NAME VARCHAR2(40))

INSERT INTO T VALUES (1,'JAMES');
INSERT INTO T VALUES (1,'DOLLY');
INSERT INTO T VALUES (2,'MICHEAL');
INSERT INTO T VALUES (2,'FLASH');
INSERT INTO T VALUES (3,'JAMES');
INSERT INTO T VALUES (3,'MARY');
INSERT INTO T VALUES (4,'JAMES');
INSERT INTO T VALUES (4,'DOLLY');
INSERT INTO T VALUES (5,'JAMES');
INSERT INTO T VALUES (5,'DOLLY');
INSERT INTO T VALUES (6,'JAMES');
INSERT INTO T VALUES (6,'MARY');

SELECT * FROM T ORDER BY 1

ID NAME
1 JAMES
1 DOLLY
2 MICHEAL
2 FLASH
3 JAMES
3 MARY
4 JAMES
4 DOLLY
5 JAMES
5 DOLLY
6 JAMES
6 MARY

each 'ID' has two values always. I want to rank the data based on same pair 'name' in an 'ID'

for example, my desired output is:

ID NAME RANK
1 JAMES 1
1 DOLLY 1
2 MICHEAL 1
2 FLASH 1
3 JAMES 1
3 MARY 1
4 JAMES 2 ---> THAT IS RANK 2 BECAUSE THIS IS THE 2ND TIME JAMES AND DOLLY ARE IN THE SAME 'ID'
4 DOLLY 2 -----> SAME AS ABOVE
5 JAMES 3 ---> THAT IS RANK 2 BECAUSE THIS IS THE 3RD TIME JAMES AND DOLLY ARE IN THE SAME 'ID'
5 DOLLY 3 -----> SAME AS ABOVE
6 JAMES 2 ---> THAT IS RANK 2 BECAUSE THIS IS THE 2ND TIME JAMES AND MARY ARE IN THE SAME 'ID'
6 MARY 2 -----> SAME AS ABOVE

I want the output in exactly above format.
