You are enabling NSF for IS-IS. What are two advantages of Cisco NSF variation over IEFT NSF? (Choose two.)

Cisco NSF can operate independently of neighbor router capabilities because it leverages internal mechanisms for graceful restart without explicit neighbor signaling.

Both Cisco NSF and IETF NSF aim to continue forwarding packets during a restart, so this is not a unique advantage of Cisco NSF over IETF NSF.

NSF and NSR are distinct mechanisms, and while Cisco implementations might support both, NSF itself does not inherently provide NSR as an additional feature.

This describes a general interaction for NSF, but IETF NSF specifically relies on NSF-aware neighbors to exchange capability information, making this a general NSF characteristic rather than a unique Cisco advantage.

Cisco NSF supports Stateful Switchover (SSO) with a standby Route Processor, allowing the standby RP to seamlessly take over forwarding and routing responsibilities upon a fault in the active RP.
