I'm setting up a network on GNS3 with the end goal of configuring VxLAN. I routed 3 Arista vEOS router together and each of them has a host attached. With basic L3 routing, everything works. I need every host to be in VLAN 100. To do so, I moved the eth12's (directly connected to a host) IP address to VLAN 100's interface, put eth12 in switchport access mode, and made sure that everything was up and running. Here are the exact configs I used:
int vlan 100
ip add 10.0.0.254/24
switchport mode access
switchport access vlan 100
When I enter "show ip int brief", eth12 is up/up with no ip address assigned and VLAN 100 is down/lowerlayerdown. When I enter "show vlan", VLAN 100's only port is Cpu (no idea what that is). There is also no connectivity between host and router
This is my first time working on something like this and I followed Arista's documentation as best as I could. I'm sorry if this is a dumb question, but I couldn't find anything else out here.
