The value of vRtrMplsGeneralSrlgFrr specifies whether Shared Risk
Link Group (SRLG) constraint will be used in the computation of
FRR bypass or detour to be associated with any primary LSP path
on the system. When the value of vRtrMplsGeneralSrlgFrr is
'true' the use of SRLG constraint is enabled.
By default, the use of SRLG constraint is disabled.
