Delaying resource reservation protocol label-switched path signaling through a restarting network device

A network device, comprising:

• one or more memories;
• and
• one or more processors to:
• receive resource reservation protocol (RSVP) path request messages from a plurality of core network devices located at a first site separate from a second site associated with the network device;
• generate an RSVP path error message, with an overload error code and a timeout period, after the network device is online within the timeout period;
• provide the RSVP path error message to the plurality of core network devices to cause the plurality of core network devices to wait for expiration of the timeout period, after the network device is fully online, until resending the RSVP path request messages;
• receive new RSVP path request messages from the plurality of core network devices after expiration of the timeout period after the network device is fully online;
• and
• establish, based on the new RSVP path request messages, label-switched paths with the plurality of core network devices, via a plurality of fabric network devices located at the second site.

A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a network device, cause the network device to:
• receive resource reservation protocol (RSVP) path request messages from a plurality of core network devices located at a first site separate from a second site associated with the network device;
• generate an RSVP path error message, with an overload error code and a timeout period, after the network device is online within the timeout period;
• provide the RSVP path error message to the plurality of core network devices to cause the plurality of core network devices to wait for expiration of the timeout period, after the network device is fully online, until resending the RSVP path request messages;
• receive new RSVP path request messages from the plurality of core network devices after expiration of the timeout period after the network device is fully online;
• establish, based on the new RSVP path request messages, label-switched paths with the plurality of core network devices, via a plurality of fabric network devices located at the second site;
• and
• receive traffic from the plurality of core network devices, via the label-switched paths and the plurality of fabric network devices located at the second site.
