EIGRP (NBMA: Multipoint): Neighbor command and Split horizon problem in NBMA

EIGRP is using multicast address 224.0.0.10 to automatically form neighborship among neighbours, however this nature can be changed by using the keyword neighbor. You will need to specify the address of your neighbor and instead of multicast. unicast is used to form neighborship. EIGRP will stop sending multicast packet on that surface. To manually add … Continue reading EIGRP (NBMA: Multipoint): Neighbor command and Split horizon problem in NBMA

EIGRP: Configuration and verification Part1

Scenario: You are tasked to configure EIGRP routing among various departments. Loopback1 of R1 is Engineering, loopback2 of R2 is Marketing, loopback3 of R3 is Sales. All physical connections have already been installed as shown in this logical network diagram. You do not need to configure anything on the switch. The switch has a localized … Continue reading EIGRP: Configuration and verification Part1
