CCNP Command Practice 2 Flashcards
Configure EIGRP
Is the wildcard mask required? If not, what happens?
(config)# router eigrp {asn}
(config-router)# network {ip address} {mask}
Wildcard mask is not required. If no wildcard mask is specified the network is summarized to the nearest major network boundary.
Displays changes with EIGRP neighbors
(config-router)# log-neighbor-changes
Configure EIGRP bandwidth
(config-if)# bandwidth x
Measured in kilobits
Enable or disable EIGRP auto-summary
(config-router)# auto-summary
no auto-summary
Configure EIGRP manual summarization
(config)# interface
(config-if)# ip summary-address eigrp {asn} {ip address} {mask} {admin distance}
Configure an EIGRP passive interface
Configure all interfaces as passive
(config)# router eigrp
(config-router)# network {ip address}
(config-router)# passive-interface [default/interface]
Create a pseudo passive EIGRP interface
(config)# router eigrp
(config-router)# network
(config-router)# distribute-list {#/prefix/route-map} out {interface}
(config)# access-list {#} deny any
Inject default route into EIGRP using a static route
(config)# ip route 0.0.0.0 0.0.0.0
(config)# router eigrp {asn}
(config-router)# redistribute static
Inject a default route into EIGRP using the IP default network command
(config)# router eigrp {asn}
(config-router)# network {ip address}
(config) #ip route 0.0.0.0 0.0.0.0 {next hop}
(config) #ip default-network {network address}
Inject a default route inte EIGRP by summarizing to 0.0.0.0/0
(config)# router eigrp {asn}
(config-router)# network {ip address}
(config-if)# ip address {ip address} {mask}
(config-if)# ip summary-address eigrp 0.0.0.0 0.0.0.0 {asn} 0.0.0.0 0.0.0.0 [admin distance]
Accept default routing information into EIGRP
(config)# router eigrp {asn}
(config-router)# default-information in
Note: add no to not accept default information
Change maximum paths EIGRP
(config)# router eigrp {asn}
(config-router)#maximum-paths {paths}
Change the EIGRP variance
(config)# router eigrp {asn}
(config-router)# variance n
Configure EIGRP bandwidth use
(config)# interface {interface}
(config-if)# bandwidth x
(config-if)# ip bandwidth-percent eigrp {asn} {percent}
Configure EIGRP authentication
(config)# key chain {name}
(config-keychain)# key {number}
(config-keychain-key)# key-string {string}
(config-keychain-key)#accept-lifetime xxxxxxx
(config-keychain-key)#send-lifetime start-time xxxx
(config-keychain-key)accept-lifetime start-time xxxx
(config)#interface {interface}
(config-if)# ip authentication mode eigrp {asn} md5
(config-if)# ip authentication key-chain eigrp {asn} {name}
Configure an EIGRP stub network
What are the options?
Which are enabled by default?
(config) # router eigrp {asn}
(config) # eigrp stub
Connected, static, summary, and receive-only.
Connected and summary are enabled by default
Manually configure EIGRP neighbor
Will communication be sent unicast or multicast?
(config)# router eigrp {asn}
(config-router)# network {network}
(config-router)# neighbor {ip address}
unicast
Warning: This disables multicast on the interface
Configure EIGRP over frame-relay dynamic mappings
(config)# interface {interface}
(config-if)# ip address {ip address} {mask}
(config-if)# encapsulation frame-relay
(config)# router eigrp {asn}
(config-router)# network {ip address}
Note: Split horizon is disabled by default on the physical interface
