A Cisco Catalyst 6500 Series Switch suffers a supervisor failure. Which statement is true regarding Cisco NSF functionality?
A. The line cards are reloaded.
B. The neighbouring routers do not participate in Cisco NSF .
C. The Cisco Express Forwarding cache is pruned.
D. Layer 3 reconvergence does not occur.
E. Cisco NSF can be deployed with RPR+.
Cisco NSF/SSO evolved from a series of progressive enhancements to reduce the impact of specific network outages. Cisco NSF/SSO builds on the earlier work known as Route Processor Redundancy (RPR) and RPR Plus (RPR+). Through the use of redundant intra-chassis hardware (redundant route processors) and the separation of the control plane from the data plane, continuous packet forwarding with zero packet loss can now be achieved, even if a hardware or software problem causes a route processor failure.
