[c-nsp] Source failure in PIM SSM

[alaerte.vidali at nsn.com]

Hi,

Any recommendation for docs handling source failure when PIM SSM is
used?

Example:

Source 1.1.1.1, group 239.1.1.1 -----R1--------R2--PC_joined 239.1.1.1
using IGMPv2

R2 has SSM mapping group 239.1.1.1 to sorce 1.1.1.1

I have seem 2 options: Anycast and Prioritycast. Would like to here
other opinion.

Tks,
Alaerte
