Module: CIENA-CES-MPLS-MIB
OID (symbolic): CIENA-CES-MPLS-MIB::cienaCesGmplsDynamicIngressCoroutedTunnelTTLPolicy
OID (numeric): 1.3.6.1.4.1.1271.2.1.18.1.2.4.1.13
Node type: OBJECT-TYPE
Type: TTLPolicy
Access: read-only
Description: Specifies whether TTL is fixed or inherited from the frame.
What is cienaCesGmplsDynamicIngressCoroutedTunnelTTLPolicy?
This specifies whether this dynamically-signaled co-routed tunnel imposes a fixed TTL on its MPLS label or inherits the TTL from the encapsulated frame, applying uniformly to both directions of the bidirectional circuit. An admin sets this to fixed for the usual core-hiding reason, which is especially relevant here since a dynamic co-routed tunnel's actual hop count can vary across re-signals in both directions at once. For example, a fixed TTL policy here keeps customer traceroutes free of visible core hops in both directions even as the tunnel silently re-signals over paths with different hop counts.
