The time in milliseconds to hold a failed LDP Hello adjacency to distinguish between LDP peer failure and interface failure.

This field is used to ensure that LDP retains adjacency multi-link LSPs during peer restart recovery when the peer restarts and an LDP Hello adjacency goes down before the LDP session.

When an LDP Hello adjacency fails, Path Manager waits until the adjacency holding timer expires before tearing down any LSP out segments associated with the adjacency.

If the LDP session fails before the adjacency holding timer expires, Path Manager performs peer restart recovery instead of tearing down any LSP out segments.

If the adjacency holding timer expires and the LDP session is still active then Path Manager assumes that the interface has failed but the peer is still active. In this case Path Manager tears down LSP out segments associated with the adjacency.

The value chosen should be large enough for the LDP session to fail if the LDP peer has failed.

Only used if _restart_capable_ is set to AMB_TRUE, and cannot be modified when the _row_status_ is ACTIVE.
