BDI replacing Vlan config on N520

Adcom911
Level 1
Level 1

Hello,

I'm trying to get a N520 configured to take over for ME3400 we are replacing. I'm not too familiar at all with Bridge Domain being a replacement for vlans. I'm trying to test a Environment monitor on gig 0/0/0 to be reachable on vlan 16. I'm trying to wrap my head around why my config works with the Mgmt-intf VRF to ping the default gateway at 192.168.16.3 but it does not work under the global routing table with the same configs and setup as the mgmt VRF. I'm thinking im missing something related to the BDI configs on the other side to the 3750??

Hi @Adcom911 ,

Port gi1/0/12 on the 3750 is configured as access (untagged). You therefore need to use untagged on the facing port on the NCS520 (gi0/0/1)

interface GigabitEthernet0/0/1
service instance 16 ethernet
encapsulation untagged

Hey @Harold Ritter ,

Thank you for replying!! I did change that to untagged but am still unable to ping out under the VRF RADIO. Is there any additional configurations needed on the 3750 side? Is this even the right application for BDI's to replace the vlan?
