Which two characteristics apply to Cisco Catalyst 6500 Series Switch supervisor redundancy
using NSF? (Choose two.)
A.
independent of SSO
B.
NSF combined with SSO enables supervisor engine load balancing
C.
supported by RIPv2, OSPF, IS-IS, and EIGRP
D.
supports IPv4 and IPv6 multicast
E.
prevents route flapping
F.
dependent on FIB tables
Explanation:
The purpose of NSF is to enable the Layer 3 switch to continue forwarding packets from an
NSF-capable neighboring router when the primary route processor (RP) is failing and the
backup RP is taking over. So it prevents the route flapping and it depends on FIB
(Forwarding Information Base) table.
