What is jnxMvpnSpmsiConfigCmcastSourcePrefixLen?

The prefix length applied to the C-multicast source address for this S-PMSI configuration; a source of 0 (or ::0) with prefix length 32 (or 128) means a wildcard source, while prefix length 0 means any source. An admin sets this alongside the source address to define exactly which multicast source traffic triggers the switch to a selective provider tunnel.
