Hello,

Are MsgIds used only for stable states refresh messages or also for trigger 
messages. RFC2961 mentions using for any RSVP message - would mean they are 
used for PATHTEAR, RESVTEAR etc.

Suppose I have setup-

Node1 ----- Node2 ------ Node3 ------ Node4

Both bundling and msgids used only between Node2 and Node3. I have one lsp 
from Node1 to Node 4 and it is in stable state. Now I setup one more lsp 
from Node1 to Node4. PATH message for this new lsp reaches Node2 and it 
suppose happens to coincide at the same time as Node2 is sending its Summary 
refresh for the first lsp. Cuz of bundling would this ACK be piggy-backed on 
the trigger PATH for the new lsp. If so would the destination IP of bundled 
packet be changed to next-hop of Node3 or would it still be Node4 (cuz PATH 
is being sent to Node4)
