I currently have a flat layer 2 network (same VTP domain) with 3 pairs of devices (4503e, 6509 and Nexus 7010). Each of the devices has trunk connections between them. Each device is also on the same network (VLAN 1) and is running EIRGP. The 6509 has the VLAN interfaces for the user networks (vlan 17, 18, etc). When I migrate a VLAN interface from the 6509 to either the 4503e or Nexus 7010 the EIGRP routes do not move to the new devices. If I add an EIGRP network statement for that particular network to the configuration, EIGRP and routing behave as expected. I don’t want use network statements. I would prefer to use redistribute connected. I can’t help but think that all I need to do is a soft refresh of the EIGRP process after I move a VLAN interface. Something that tells EIGRP to there is a new connected network.
In the sample config below, I am show VLAN 18 which is one of the user networks that has moved.
