Hi,
Is it possible to tune metric on links in ring to get the most nodes on the
ring protected by the LFA?
RFC 5286
3.2. Node-Protecting Alternate Next-Hops
For an alternate next-hop N to protect against node failure of a
primary neighbor E for destination D, N must be loop-free with
respect to both E and D. In other words, N's path to D must not go
through E. This is the case if Inequality 3 is true, where N is the
neighbor providing a loop-free alternate.
Distance_opt(N, D) < Distance_opt(N, E) + Distance_opt(E, D)
Inequality 3: Criteria for a Node-Protecting Loop-Free Alternate
