Loopback0 problem

Post by Alcanoob123 » 28 Oct 2019 09:01

Hello,

I am having a problem configuring the Loopback0 address on the OS6465. I am using the 6465 as a replacement for the 6250 that is no longer being made. In the 6250, I would configure a mgmt address on /32, vlan 2816, and then the Loopback0 address would be given the same ip. The 6465 no longer allows this. Please see example below:

6250:

ip interface mgnt_vlan address 10.28.16.2 mask 255.255.255.240 vlan 2816
ip interface Loopback0 address 10.28.16.2
ip static-route 0.0.0.0 mask 0.0.0.0 gateway 10.28.16.1 metric 1

6465:

+++ address for Loopback0 (10.28.16.2/255.255.255.255) conflicts with address for mgnt_vlan (10.28.16.2/255.255.255.240)
ERROR: Ip Address must not conflict with interface mgnt_vlan

My apologies, I am brand new to this site, and as you can see, new to networking.

In your case loopback0 is not necessary to configure. You need only the both other lines.
