This is the keepalive hold time the remote peer advertised for this session at the time it was established, reflecting the peer's configuration rather than this device's own settings, and like its local counterpart can go stale relative to the peer's current configuration. An admin diagnosing an asymmetric keepalive timeout between two LDP peers would compare this value against cienaCesLdpSessionConfiguredHoldTime to see exactly what each side agreed to at session setup. A large mismatch, say the peer advertising 10 seconds against a local 45, would explain a session that's more sensitive to transient peer-side delays than expected.
