MPLS TE reoptimization

Does MPLS TE reoptimization cause packet loss or not? And what happens with "old tunnel"? Is it teared down or maintained?

MPLS TE reoptimization

Hi Volodymyr,

In MPLS TE, there is a notion of "make before break", where the new tunnel will be signaled before the old tunnel is taken down. This prevents packet loss.
