Question Of The Day: 12 May, 2008

Topic: RIP

r1 is a high-end router running RIP on it’s connection to the low-speed router r2.  The site engineer for r2 has noticed that the routing table on r2 is losing RIP routes.  He thinks that your r1 is sending RIP updates too quickly for r2 to process.  Configure r1 to implement a 25 millisecond delay between RIP packets.

Question Of The Day: 06 May, 2008 

Topic: EIGRP

Limit r1’s FastEthernet0/0 interface to only be able to use up to 3Mbps for EIGRP traffic.

router eigrp 100
 no auto-summary
 network 10.1.12.1 0.0.0.0
!
interface FastEthernet0/0
 ip address 10.1.12.1 255.255.255.0
 speed 100
 duplex full

Answer:

interface fa0/0
 ip bandwidth-percent eigrp 100 3

By default, EIGRP can use up to 50% of an interface’s bandwidth.  You can control that percentage with the ‘ip bandwidth-percent eigrp’ command.

ip bandwidth-percent eigrp

Usage Guidelines
EIGRP will use up to 50 percent of the bandwidth of a link, as defined by the bandwidth interface configuration command. This command may be used if some other fraction of the bandwidth is desired. Note that values greater than 100 percent may be configured. The configuration option may be useful if the bandwidth is set artificially low for other reasons.

In our example, r1’s fa0/0 interface is hard-set to 100Mbps so we need to limit EIGRP to 3% of that bandwidth.
