Question Of The Day: 10 April, 2008

Topic: Frame Relay Traffic Shaping

The network engineer in charge of r1 recently configured Frame Relay Traffic Shaping.  The remote sites have complained that they are still getting too much traffic ingress on their Frame Relay connections to r1.  You agree to look at his configuration:

map-class frame-relay FRTS
 frame-relay cir 256000
 frame-relay be 12880
 frame-relay mincir 128000
 frame-relay adaptive-shaping becn
!
interface Serial1/0
 ip address 10.1.1.1 255.255.255.0
 encapsulation frame-relay
 frame-relay class FRTS
 frame-relay map ip 10.1.1.2 102 broadcast
 frame-relay map ip 10.1.1.3 103 broadcast
 no frame-relay inverse-arp

r1#sh frame map
Serial1/0 (up): ip 10.1.1.2 dlci 102(0x66,0x1860), static,
              broadcast,
              CISCO, status defined, active
Serial1/0 (up): ip 10.1.1.3 dlci 103(0x67,0x1870), static,
              broadcast,
              CISCO, status defined, active

What is the problem with this configuration?


Yesterday’s Question

Question Of The Day: 09 April, 2008 

 Topic: IP Prefix Lists

Write a single line IP prefix list called “MY_SUBNETS” that will only allow the following subnets:

10.1.1.118/26
10.1.1.118/27
10.1.1.118/28
10.1.1.118/29
10.1.1.118/30

Answer: ip prefix-list MY_SUBNETS 10.1.1.118/26 le 30

When matching on multiple, contiguous IP subnets, your ip prefix-list should be in the form: ip prefix-list NAME permit x.x.x.x/[min mask] le [max mask]

ip prefix-list

  3. @f – Good catch. Damn these fat fingers!!! It’s supposed to be .118, not .128.
