SRefresh msgs can used only if the corresponding PATH/RESV trigger msgs have been sent with MSG_ID objects. That's how you can associate the states.. MSG_ID_ACK/NACK can be either sent in seperate msgs or piggybacked in other msgs.. Bundle msgs are always addressed to the immediate RSVP peer. The sub-msgs contained inside the bundle msgs are themselves complete msgs with their own rsvp header.. with regards, Rajeev -----Original Message----- From: Sandeep S [mailto:san_101@hotmail.com] Sent: Thursday, November 01, 2001 1:50 PM To: mpls@UU.NET Subject: questions related to Refresh reduction 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) _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp |
