RE: [tipc-discussion] tipc stops working if one blade re-config tipc with a different network address

[Stephens, A. <all...@wi...>]

Hi Lijun:

If you have a pair of TIPC nodes, A and B, and node B is reconfigured to
use a new node address, then TIPC should end up having 2 links on node
A: one link using B's new address and the other using B's original
address; the first link will be "up" and the second link will be "down".

I have frequently uninstalled and reinstalled TIPC 1.5 using different
node addresses, and have never encountered problems where communication
is not successfully re-established as described above.  I just re-tried
it now using TIPC 1.5.09, but I have no reason to believe it shouldn't
also work the same way with TIPC 1.5.05.

Is this problem 100% reproducible for you?  If not, you may be seeing
another instance of the "name table inconsistency" problem you
previously reported.

Regards,
Al=20
