Solved: Re: urgent issue between core and Distribution - Page 2

coolj_212 · ‎08-12-2018

I configure ospf l3 between core switch and distribution and after 3 days I lose the connectivity between the core, Distribution and access switch after I restart the Distribution the network become normal the configuration that have been done as layer 3 is below and also I observe that one of the Distribution hang Also note that we did The below configuration in different 3 site and its working Find so please anyone have the same issue please advice

I think the neighbour went down or had an issue due to poor link light levels.

You restarted the switch and it possibly brought the neighbour up for now but if the light levels are poor chances are it will happen again.

use un all command to disable debugging if you haven't done already :)

hello i configure the Distribution from L3 TO L2 and it was working Fine so configure it as L3 OSPF Between the cor and Distribution so its work for 3 days Fine and there is vss between Dis 1 and Dis 2 after 3 days the I lose the ospf between the core Dis I went to chick from the Dis Site I found the VSS is not working
