EIGRP应该占用带宽问题

1. How do you turn off EIGRP Autosummarization?
BSCN, p. 267
Router(config)#router eigrp 1
Router(config-router)#network 10.0.0.0
Router(config-router)#network 172.16.0.0
Router(config-router)#no auto-summary
2. How do you force EIGRP summarization?
BSCN, p. 267
Router(config)#router eigrp 1
Router(config-router)#network 10.0.0.0
Router(config-router)#network 192.168.4.0
Router(config-router)#int s 0
Router(config-if)#ip address 192.168.4.2 255.255.255.0
Router(config-if)#ip summary-address eigrp 1 172.16.0.0 255.255.0.0
3. What command do you use to adjust the EIGRP link utilization?
BSCN, p. 270
"
The percent parameter can be set to a value greater than 100. This is useful if
the bandwidth is configured artificially low for routing policy reasons. ...a
configuration that allows EIGRP to use 40 kps (200 percent of the configured
bandwidth) on the interface"
_______________________
Router(config)#int s 0
Router(config-if)#bandwidth 20
Router(config-if)#ip bandwidth-percent eigrp 1 200
Router(config-if)#bandwidth ?
<1-10000000> Bandwidth in kilobits
Router(config-if)#ip bandwidth-percent eigrp 1 ?
<1-999999> Maximum bandwidth percentage that EIGRP may use
4. The figure below represents a Frame-Relay Multipoint topology in which all
VCs are to share bandwidth evenly. How would you configure the bandwidth
portion of this? BSCN, p. 271, Figure 5-13
Router(config)#int s 0
Router(config-if)#encapsulation frame-relay
Router(config-if)#bandwidth 224
5. The Frame-Relay Multipoint Network below has different CIRs. How would you
configure it so as not to overwhelm the slowest speed circuit?
BSCN, p.272, Figure 5-14
Router(config)#int s 0
Router(config-if)#encapsulation frame-relay
Router(config-if)#bandwidth 224
6. EIGRP: What hybrid solution configuration that combines Frame-Relay
Multipoint and Point-to-Point would make the best use of bandwidth for the
diagram below? BSCN, p. 272, Figure 5-15
Router(config)#interface serial 0.1 multipoint
Router(config-subif)#bandwidth 768
Router(config-subif)#interface serial 0.2 point-to-point
Router(config-subif)#bandwidth 56
7. Using EIGRP, configure the bandwidth for the Frame-Relay hub-and-spoke
network below: BSCN, p. 273, Figure 5-16
RouterC(config)#int s 0
RouterC(config-if)#encapsulation frame-relay
RouterC(config-if)#interface serial 0.1 point-to-point
RouterC(config-subif)#bandwidth 25
RouterC(config-subif)#ip bandwidth-percent eigrp 63 110
<sub-interfaces 0.2 thru 0.9 omitted>
RouterC(config-subif)#interface serial 0.10 point-to-point
RouterC(config-subif)#bandwidth 25
RouterC(config-subif)#ip bandwidth-percent eigrp 63 110
__________________
interface Serial 0
bandwidth 56
ip bandwidth-percent eigrp 109 75
就是允许s0使用带宽为42k
interface Serial 1
bandwidth 128
ip bandwidth-percent eigrp 210 200
根据上一条，你可以计算出这里使用的带宽
