Re: BDI configuration N520-20G4Z-A

Adcom911 · ‎06-11-2024

Hello,

I'm trying to get a N520 configured to take over for ME3400 we are replacing. I'm not familiar at all with Bridge Domain being a replacement for vlans. 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??

Config from N520

why you not use Port Channel and instead you use BDI and make Loop?

Adcom911 · ‎06-12-2024

Hello,

I thought BDI is the replacement for vlans on the N520. So I was trying to test vlan 16/bdi 16 on the N520 by doing this setup.

MHM Cisco World · ‎06-12-2024

you already config port with tag so no need BDI
correct me if I am wrong
MHM

Adcom911 · ‎06-12-2024

So I would need to remove the service instance portion of the config?

Hello,

try and remove the 'ip default-gateway 192.168.16.3' from the config.

Also, can you post the full running config of the 3750 ?

Tried that and no luck

Hello,

I might be completely off here, but can you try and add:

interface BDI16
description Vlan 16
--> encapsulation dot1q 16
ip address 192.168.16.48 255.255.255.0
cdp enable

Adcom911 · ‎06-13-2024

No luck with that one. Its just weird to me that I can reach the gateway via the Mgmt-intf but not within the global routing table that has the same routes and config setup.
