Hi all,
we have 3 site conneted with OSPF , on each site we have 2 Routers M120 (junos 8.5R4.3) and 4switch
Site2router1
|
site1 Router1 ------ site3Router1 ---- sw1----Sw4
| | \ / |
| | / \ |
site1 router2 ----- site3 Router2 ---- Sw2----Sw3
|
site2router2
we have VRRP configured on in interface connected to switch ,and ospf configured betwen routers , but not in interface with switch .
the problem : is when loopoccur on our switchs of site 3 ( error configuration of STP ) , in routers of site 3 we had : first : VRRP flap (master /buckup) on router2 and, then OSPF become down with all their neighbor (=>MPLS Down)
Question: Why OSPF come Down when loop occur on switchs ?
is this a Junos Bug ??
attched file the log messages
Thank you!
