As I understand it, you try to use the SAME NslpApi object and regsiter it for two NSLP IDs. As I understand my code, you should get a GistException saying "This socket already registered for a diffrent NSLP ID". Don't you get this one?

Hello all!

I've got a little problem here, and I do not know the reason.

It's about message reception.

My topology:

A-B-C

A is RMD-Ingress B is RMD-Core C is RMD-Egress (modified QoS-NSLPs running everywhere above GIST)

A does dual message sending: sends a reserve to C with

C-mode on, and another reserve to C with D-mode on. (using ip-of-A and ip-of-C in mri)

B registers only for NSLP-ID 4 (intra-domain), while C registers for both 4 and 6 ids, to get both intra-domain A-B-C and A-C edge2edge only messages.

Problem is, C only receives edge2edge message, but not the intra-domain one. This only occurs if C registers to GIST with both NSLP-IDs. If I register only either 4 or 6, it gets the appropriate edge2edge or intra-domain reserve fine. (but just one of course).

GIST transmission is fine, I used debug mode on node C, which showed both API-Call Resvmsg-s, with the correct NSLP-ids.

I suspect the problem might be either with select() in waitforsignal() (perhaps receiving messages with a too short delay??) or the way I registered the two NSLP-ids.

I did not alter much of NslpAPI.cpp, so my guess is the latter.

Please see the attached text file for a small code snippit I use.

Thanks for the help in advance,

Ferenc Pintér
