Summary Table:Chapter 8 Command Review

Command	Description
accept-lifetime start-time { infinite end-time duration seconds }	Specifies the time period during which the authentication key on a key chain is received as valid.
auto-summary	Enables automatic summarization at network boundaries. This command is enabled by default.
bandwidth kilobits	Specifies the bandwidth parameter, in kilobits per second, on an interface.
debug eigrp packets	Displays EIGRP packet activity.
debug ip eigrp neighbor process-id address	Adds a filter to the debug eigrp packets command, telling it to display only IP packets for the indicated process and neighbor.
delay tens-of-microseconds	Specifies the delay parameter, in tens of microseconds, on an interface.
ip authentication key-chain eigrp process-id key-chain	Configures a key chain on an EIGRP interface and specifies the name of the key chain to be used.
ip authentication mode eigrp process-id md5	Enables EIGRP authentication on an interface.
ip bandwidth-percent eigrp process-id percent	Configures the percentage of bandwidth used by EIGRP; the default is 50%.
ip hello-interval eigrp process-id seconds	Configures the EIGRP hello interval.
ip hold-time eigrp process-id seconds	Configures the EIGRP hold time.
ip summary-address eigrp process-id address mask	Configures a router to send a summary EIGRP advertisement.
key number	Specifies a key on a key chain.
key chain name-of-chain	Specifies a group of authentication keys.
key-string text	Specifies the authentication string, or password, used by a key.
metric weights tos k1 k2 k3 k4 k5	Specifies how much weight the bandwidth, load, delay, and reliability parameters should be given in the IGRP and EIGRP metric calculations.
network network-number	Specifies the network address of one or more interfaces on which IGRP, EIGRP, or RIP processes should be enabled.
passive-interface type number	Disables the transmission of broadcast or multicast routing updates on an interface.
router eigrp process-id	Enables an EIGRP process.
send-lifetime start-time { infinite end-time duration seconds }	Specifies the time period during which the authentication key on a key chain may be sent.
show ip eigrp neighbors [ type number ]	Displays the EIGRP neighbor table.
show ip eigrp topology [ process-id [[ ip address ] mask ]]	Displays the EIGRP topology table.
timers active-time { minutes disabled }	Changes or disables the default 3-minute active time.
traffic-share { balanced min }	Specifies whether an IGRP or EIGRP routing process should use unequal -cost load-balancing or equal-cost load balancing only.
variance multiplier	Specifies a route multiplier by which a route metric can vary from the lowest -cost metric and still be included in an unequal-cost load-balancing group.
