Description: Source IP address of the dynamic decap tunnel.
What is cienaCesGmplsDynamicEgressUniDirTunnelPrevHopIpAddr?
This is the IP address of the neighboring router immediately upstream of this device on the tunnel's path, i.e., the last hop before decapsulation happens here. When a decap tunnel stops receiving traffic, this is the address you ping and check label-forwarding tables on first, since it's the one neighbor that's supposed to be sending this device labeled packets to strip. For tunnel 'BOS-DC-GW-01', this might read 10.88.47.208 — the router one hop closer to the tunnel's origin.
