Peter,

But that "mandate" was fixed by Ina, Bruno and Jean-Louis in 2008 :) https://datatracker.ietf.org/doc/html/rfc5283 In these multi-area deployments > the host routes are sent everywhere, updates are triggered regardless of > the failure type. IGPs are effectively providing liveness service > between PEs in any MPLS network. > That is true too - as folks just do not know how to configure BGP properly (if BGP is used for services). That leaves us the space what to do where there is no BGP carrying services. Or BGP implementation is broken and can not do the right thing. For the pulse proposal - no one answered the question posted what is a definition of mass failure. But maybe that will be the secret sauce of a vendor :) ? The fact that we are all in agreement that some network events will not work that well with the proposed solution seems to be a sufficient reason for me to consider different solution(s). Thx, R.
