Folks,

Happy Monday!

As I was painting this weekend, I remembered that the use-case for IPv6 Header insertion is TI-LFA. This made the following questions come to mind:


  *   How does TI-LFA work when the original packet already contains a routing header? Will it insert a second, so that the packet has two routing headers?
  *   How does TI-LFA work when the node directly upstream of the link (i.e., the PLR) is not a segment endpoint? Will it insert an routing header? Is that consistent with 8200?

                                                                                                                        Ron
