Access list policy with odd and even filtering

Last updated on December 23, 2018

        I'm having some issues with some access list configuration regarding a topology. The lab requirements are:
  • Deny any host with even-numbered IP addresses from the BM_R1 LAN from accessing hosts on the BM_R3 LAN.
  • Hosts with odd-numbered IP addresses on the BM_R1 LAN should be able to ping any other destination.
The two networks to which the access list refers are (R3 LAN) and (R1 LAN). I've tried changing the wildcard bits to for even IP addresses on both. I've also tried placing them on either R1 or R3, but it did not work. What am I doing wrong?
