Abstract:
LSP Self-ping is a new, light-weight protocol that ingress LSRs can
use to verify an LSPs readiness to carry traffic. LSP Self-ping does
not consume control plane resources on the egress LSR.
When an ingress LSR executes LSP Self-ping procedures, it constructs
a probe message. The probe message is an IP datagram whose
destination address represents an interface on the ingress LSR.
The ingress LSR forwards the probe through the LSP under test. If
the LSP is ready to forward traffic, the egress LSR receives the
probe. Because the probe is addressed to the ingress LSR, the egress
LSR forwards the probe back to the ingress. When the ingress LSR
receives the probe, it has verified LSP readiness without consuming
control plane resources at the egress LSR.
