vRtrMplsLspDecrementTtl
Module: ALCATEL-IND1-TIMETRA-MPLS-MIB
OID (symbolic): ALCATEL-IND1-TIMETRA-MPLS-MIB::vRtrMplsLspDecrementTtl
OID (numeric): 1.3.6.1.4.1.6527.3.1.2.6.1.1.14
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-create
Description: When the value of vRtrMplsLspDecrementTtl is 'true', the ingress ESR writes the TTL of the IP packet into the label and each transit ESR decrements the TTL in the label. At the egress ESR the TTL value from the label is written into the IP packet.
When the value of vRtrMplsLspDecrementTtl is 'false', the ingress ESR ignores the IP packet TTL and writes the value of 255 into the label; and the egress ESR does not write the label's TTL into the IP packet.
What is vRtrMplsLspDecrementTtl?
Controls whether the IP packet's Time-To-Live (TTL) value is propagated into and decremented through the MPLS label at each hop. When enabled, each transit router decrements the TTL, making the MPLS path visible to traceroute and hop-count limiting.
