Network problems

[cpacho]

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, 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

[cpacho]

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.

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

R1:

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
