Spanning tree? -----Original Message----- From: juniper-nsp-boun...@puck.nether.net [mailto:juniper-nsp-boun...@puck.nether.net] On Behalf Of Gökhan Gümüs Sent: Monday, March 14, 2011 12:14 PM To: Keegan Holley Cc: juniper-nsp@puck.nether.net Subject: Re: [j-nsp] Too much packet loss during switchover on MPLS network
Thanks for the updates... Yes i enabled node-link-protection and link protection respectively. Results are same. LSP change from primary to secondary occurs immediately as i can see it from mpls logs. I have no problem on it. I am talking about customer traffic. Customer is sending ping packets continuosly and during that time i shut one interface down which is triggering a transition from primary to secondary.After that customer experienced packet loss for 41 seconds. MPLS LSPs are being used for VPLS traffic. I have no visibility on Layer 3 side on customer.
