Description (partial)


Error messages printed by ISIS:

isis[1006]: %ROUTING-ISIS-3-SRGB_FREE_ERR : SRGB free Error: 'SRGB-free failed for start_lbl 16000 size 8000. (So far fail 176) srgb=(16000 23999, SRGB_FREE_PENDING, 0x3): 0x42d39c00, 'MPLS_LSD' detected the 'warning' condition 'Label is bound to a FPI''

SR labels not being programmed in RIB and LSD, because old SRGB is not freed and therefore new SRGB is not getting allocated.

Problem happend when SRGB is changed, while there is a node with strict SPF SID only (without having a regular SID).
