The value of vRtrMplsLspPathSrlgDisjoint specifies whether the
relevant standby lsp path is SRLG disjoint from the associated primary
lsp path for an LSP at the head-end Label Edge Router (LER).
The value vRtrMplsLspPathSrlgDisjoint is used only when the
value of vRtrMplsLspPathType is 'standby'. When the value of
vRtrMplsLspPathSrlgDisjoint is 'true', primary and standby lsp
path do not have SRLG membership in common. When the value of
vRtrMplsLspPathSrlgDisjoint is 'false', primary and standby lsp
path have SRLG membership in common.
