Hi,

I have question for the difference between the generation of error 'Bad
loose node' and 'no route available toward destination'.

For ex.

A -------IUT------B

1)   A sends a Path msg with the ERO as IUT connected to A interface
address, and unrecognized address and TesterB address, and set the L bits
for second unrecognized address as loose node, since there is no path
between unrecognized node and testerb, the iut should send out the path
error msg with error code 'routing problem' and error value 'bad loose
node'.

2)  A sends a path msg with ERO as  IUT connected to A interface address,
unrecognized address, but in the session object, put the end nodes as
testerB, then the iut should send the path error msg with error code
'routing problem' and error value 'no route available towards the
destination'.
or I have to test the three tests mentioned in the section 4.7.4.

If that is the case, is there any vender such as cisco or juniper, which
can configure the Exclude-any, include-any, include-all parameters on the
router?

Thanks in advance.
