Network problems

Hello;

I have a network with a ring (main) made up of 2 routers and 4 switches and a subring that shares the 2 routers and 2 new switches, as well as 2 switches in a stack connected to the routers through MLAG. Everything works correctly even when I turn off any of the Routers but when Router 1 (R1) turns the network back on it has problems for 6 minutes. And I have verified that it is the time it takes to communicate between the routers.

Hi,

 

The topology diagram looks correct but we are missing the configuration piece.  

 

Are there any relevant logs during this time period?

 

Would it be possible open a case with GTAC?

 

Thanks,

Chris Thompson

Thanks for the answer, do you think that R1 may have a hardware problem ???. Next I pass my settings;

R1:

Sorry I did not answer the other question, in the log during the start of R1 only appears the change of status of the ERPS protection-Pending-Idle and the change of Role of the vlans in the VRRP.

hi, I need to confirm that I don't have any errors in my settings before opening a TAC with Extreme, can someone help me ???

Thanks
