SEM 2 Flashcards
EIGRP metrics
bandwidth, load, delay, reliability, and MTU
CEF
utilizes an adjancey table to make forwarding decisions
switchport port-security
command to enable sp security you can set counter for max mac addresses sp must be in switchport mode access ps max n ps mac address sticky
different types of vlans
data, management, voice, native,default
VLAN trunk
enables vlans to ride on one link m 802.1q
Vlan tagging
tagged after source mac address
benefits of vlans
better security cost reduction better performance smaller broadcast domains improved IT staff efficiency simpler p[roject and application management
Why use Static routes
better security
use less bandwidth
best path is already known
disadvantages
config is prone to human error
very labor intensive setup and maintenance
admin intervention is required to maintain and change routing info
no very scalable
requires intricate knowledge of the overall network
describe the following static routes
directly connected
next hop
fully defined
dc: specifies the exit interface
nh: specifies the next hop address
fd: specifies both
Command for propagating a default route
default-information originate
default admin distance for Rip ospf and eigrp
120: RIP
110: OSPF
90: EIGRP
What are the three layers of the Cisco bordersless netowork concept
core, distribtuion, and access
core and distribution are collapsed into one for two layer
what are the primary benefits of a cisco borderless network
hierarchical, modularity, resiliency, flexibility
access layer of cisco boderless network
where the user accesses the network
helps application operate more securely
distribution layer functions
aggregation, intelligent switching and routing, high availablity trhough redundant distribution layer switching
provide differntiated services to various applications
