Hi guys
I am doing a model of OTV in which it is intended to have a link bakcup such service, the topolgia is the one below is displayed, the problem is the time it takes to converge the network when you have the fall of the first link and which is approximately 1 minute, somehow know to enhance this time or it would advisable to have high availability on the issue of the link?
