Task 4.3

The question is:
Configure the network so that hosts in VLAN8 use VLAN 18 to reach all hosts with an even number in the third octect, while VLAN 58 is used to reach all hosts with an odd number in the third octet.

Tha ans is use offset to do it.

My ans is:
router eigrp 10
network 150.30.8.8 0.0.0.0
network 0.0.0.0
distance 89 156.30.18.1 0.0.0.0 even
distance 89 156.30.58.5 0.0.0.0 odd
no auto-summary
eigrp router-id 150.30.8.8
!
!
ip access-list standard even
permit 0.0.0.0 255.255.254.255
ip access-list standard odd
permit 0.0.1.0 255.255.254.255
!


But the result seems have some problem. Beacuse some of the prefix seems not work. 156.30.15.3/32 and 156.30.35.5/32 have odd third octect, but the router show it should route to Vlan 18.
Can anyone suggest what is my problem ?
Thanks!!

  • ..i hate those /32's they have a mind of there own.

    ..somebody help me out here.... a longer match on the prefix is more preferred than administrative distance.

    ...quick google you can find something...also prove it with new loopback addressess...
  • Shouldn't the hold time be set for 4 not 5? The task says to make sure that traffic is rerouted within 5 seconds if r1 or r5 go down. If you use 5 as the hold time then it will take more than 5 seconds to converge. I set the hold time for 4 seconds.
