Hello Team, I'm going through RFC 5440 to understand PCC's responsibility upon receiving PCE Overload notification from PCE.
What I understood is as follows: *Scenario 1: PCC is connected to multiple PCE:* 1. PCC established connections with Primary PCE and all other backup PCEs. 2. PCC sends Sync LSPs and PCReq to PCE and everything goes fine. 3. PCE sends PCInitiated LSP and everything goes fine. 4. Now, PCE sends Overload Notification to PCC. >From step 4 onwards what will be expected execution steps as per RFC 5440? a. If further path computation/reoptimization requirement occurs, PCC sends those to the backup PCE? or if there are no further requests from PCC, then nothing needs to be done from the PCC side. b. What would be existing delegations? would that need to be re-delegated to backup PCE? Please add any further expected behavior/scenario if I missed anything. *Scenario 2: PCC is connected to Single PCE:* Everything would be the same as per Scenario 1 except PCC will have no other option than wait for PCE's availability. Thanks & Regards, Mrinmoy
