Hi, As a choice of fast PE protection,
1. This solution is simple and light-weight. We need not introduce the complex context label table in PE routers. So label table need not be stored repeatedly on RG members. 2. Also, it’s easy to be deployed. It does not bring any change to P routers (control plane & data plane). It even does not change the data plane of PE routers. 3. In addition, it does not bear the restriction of “no penultimate-hop-popping”. Thanks, Mingui
