I sometimes experience issues on RE failover on M- and MX-Boxes. Here's a snippet of a case I opened about a year ago: +++snip+++ the effect was that the router was left in a half-working state - IS-IS was up, most IPv4 BGP peerings were up (but not all of them), none of the IPv6 BGP peerings were up. Pings to the loopback address were not possible, we could not ping some directly attached hosts even though ARP was working fine. There were no error messages or any indication of anything being wrong. When testing locally via ping from the router CLI, we got "sendto: operation not permitted" messages. The NTP daemon was logging "sendto(x.x.x.x): Operation not permitted" (and did not work), ping to y.y.y.y (a directly attached host in the same subnet as x.x.x.x, living in z.z.z.z/27) returned the same "operation not permitted" messages, but ARP was working fine. one of the not-working BGP sessions logged this: task_connect: task BGP_remoteAS.a.b.c.d+179 addr a.b.c.d+179: Operation not permitted "restart routing" (at 05:24 CEST) did not help. +++snip+++ the remedy for this was (and has been everytime I ran into this, about once a year since 2004): remove lo0-filters, commit, activate lo0-filters, commit. The instant the commit with deactivated lo0-filters is finished, everything works properly, and continues to work even with the lo0 filters back in place. A race condition of some sort, maybe? kind regards, Felix -- Felix Schüren Head of Network ----------------------------------------------------------------------- Host Europe GmbH - http://www.hosteurope.de Welserstraße 14 - 51149 Köln - Germany Telefon: 0800 467 8387 - Fax: +49 180 5 66 3233 (*) HRB 28495 Amtsgericht Köln - USt-IdNr.: DE187370678 Geschäftsführer: Uwe Braun - Alex Collins - Mark Joseph - Patrick Pulvermüller (*) 0,14 EUR/Min. aus dem dt.
