Sorry, Which release ?
Your secondary path is well in Standby mode ? Could you enable traffic stat for LSP with a short interval ? And check during the blackholing where the LSP is broken on the path (by checking LSP stat on nodes before and after the failure ) ? thks regards David David Roy Orange - IP Domestic Backbone - TAC Tel. +33(0)299876472 Mob. +33(0)685522213 Email. david....@orange-ftgroup.com<mailto:david....@orange-ftgroup.com> JNCIE-M/T #703 ; JNCIS-ENT ________________________________ De : Gökhan Gümüş [mailto:ggu...@gmail.com] Envoyé : lundi 14 mars 2011 21:11 À : ROY David DTF/DERX Cc : Keegan Holley; juniper-nsp@puck.nether.net Objet : Re: [j-nsp] Too much packet loss during switchover on MPLS network Actually i am using MX960 routers. Did you monitor forwarding database on each PE to check if there is any change (MAC address refresh) after your 41 sec of outage ? - I need to re-test it. Currently i can not say it. Did you experience the same issue when your primary LSP comes up (and after the revert timout) ? No there is no packet loss during transition from secondary to primary.

I requested them to ping from different servers to the same destination when i shut the interface down.All of them had no reachability to the remote destinations. Could it be possible to fix it with BFD?
