This dump is valid to pass Cisco 300-320 exam and don't just memorize the answer, you need to get through understanding of it because the question changed a little in the real exam. The material is to supplement your studies.
"Out-of-band traffic flow is supported with the Cisco NAS connected to most common Cisco switches with recent software releases."
·Recommended configuration if sharing ports between IP phones and PCs."
- Multiple physical gateways participating simultaneously in packet forwarding.
- All hosts in the VLAN configured with the same default gateway address.
"It is worth noting that three most important timers to tune network for sub-second convergence are the failure detection delay, initial LSA generation delay and initial SPF delay. All other timers, such as hold and maximum time serve the purpose of stabilizing network, and affect convergence in "worst-case" unstable network scenarios."
"Benefits of OSPF LSA Throttling Prior to the OSPF LSA Throttling feature, LSA generation was rate-limited for 5 seconds. That meant that changes in an LSA could not be propagated in milliseconds, so the OSPF network could not achieve millisecond convergence. The OSPF LSA Throttling feature is enabled by default and allows faster OSPF convergence (in milliseconds). This feature can be customized. One command controls the generation (sending) of LSAs and another command controls the receiving interval. This feature also provides a dynamic mechanism to slow down the frequency of LSA updates in OSPF during times of network instability."
