Routing

Hi Team,

I am unable to put interface in logical-system EDGE-2, i have working logical-system EDGE-1

xpaul@H1-EDGE-re0> show configuration logical-systems EDGE-1 |display set
set logical-systems EDGE-1 interfaces xe-1/0/0 unit 0

xpaul@H1-EDGE-re0> show configuration interfaces xe-1/0/0 |display set
set interfaces xe-1/0/0 vlan-tagging
set interfaces xe-1/0/0 unit 0 vlan-id 2500
set interfaces xe-1/0/0 unit 0 family inet address 1.1.1.2/24 vrrp-group 4 virtual-address 1.1.1.1
set interfaces xe-1/0/0 unit 0 family inet address 1.1.1.2/24 vrrp-group 4 priority 110
set interfaces xe-1/0/0 unit 0 family inet address 1.1.1.2/24 vrrp-group 4 preempt
set interfaces xe-1/0/0 unit 0 family inet address 1.1.1.2/24 vrrp-group 4 accept-data

xpaul@H1-EDGE-re0> show vrrp logical-system EDGE-1

Not seeing VRRP output? why?

Why does this detect duplicate when i have trying these two in different logical-systems?

What happens when you have deleted the interface configurations and do a commit. And after that you create a logical-system EDGE-2 with the interface?

 

tks,

Hi abhisg,

 

Deleting the interface puts it in the logical system but then interface is not getting configured. Getting same duplicate interface error.

can you delete interface from default instance and commit.
Then add it to logical system and check?

You have configured both interfaces in root logical system. The interfaces should be configured under the logical-system EDGE-2 lie below:

set logical-systems EDGE-2 interfaces xe-1/1/0 unit 0 vlan-id 2500

set logical-systems EDGE-2 interfaces xe-1/1/0 unit 0 family inet address 1.1.1.3/24 vrrp-group 4 virtual-address 1.1.1.1
set logical-systems EDGE-2 interfaces xe-1/1/0 unit 0 family inet address 1.1.1.3/24 vrrp-group 4 priority 150
set logical-systems EDGE-2 interfaces xe-1/1/0 unit 0 family inet address 1.1.1.3/24 vrrp-group 4 preempt
set logical-systems EDGE-2 interfaces xe-1/1/0 unit 0 family inet address 1.1.1.3/24 vrrp-group 4 accept-data

set interfaces xe-1/1/0 vlan-tagging

Hi Nellikka,

 

please see my config has EDGE-2 as logical system.

 

 

Hi Xavier,

 

The entire configuration for the interfaces should be under the logical-systems hierarchy, not just binding the interface

 

Please use the below config for EDGE-1 and EDGE-2:

 

set logical-systems EDGE-1 interfaces xe-1/0/0 vlan-tagging
set logical-systems EDGE-1 interfaces xe-1/0/0 unit 0 vlan-id 2500
set logical-systems EDGE-1 interfaces xe-1/0/0 unit 0 family inet address 1.1.1.2/24 vrrp-group 4 virtual-address 1.1.1.1
set logical-systems EDGE-1 interfaces xe-1/0/0 unit 0 family inet address 1.1.1.2/24 vrrp-group 4 priority 110
set logical-systems EDGE-1 interfaces xe-1/0/0 unit 0 family inet address 1.1.1.2/24 vrrp-group 4 preempt
set logical-systems EDGE-1 interfaces xe-1/0/0 unit 0 family inet address 1.1.1.2/24 vrrp-group 4 accept-data

set logical-systems EDGE-2 interfaces xe-1/1/1 vlan-tagging
set logical-systems EDGE-2 interfaces xe-1/1/1 unit 0 vlan-id 2500
set logical-systems EDGE-2 interfaces xe-1/1/1 unit 0 family inet address 1.1.1.3/24 vrrp-group 4 virtual-address 1.1.1.1
set logical-systems EDGE-2 interfaces xe-1/1/1 unit 0 family inet address 1.1.1.3/24 vrrp-group 4 priority 110
set logical-systems EDGE-2 interfaces xe-1/1/1 unit 0 family inet address 1.1.1.3/24 vrrp-group 4 preempt
set logical-systems EDGE-2 interfaces xe-1/1/1 unit 0 family inet address 1.1.1.3/24 vrrp-group 4 accept-data

 

Hope this helps.

Pradeep.

 

 

Correction for interface vlan-tagging, use this:

 

set interfaces xe-1/0/0 vlan-tagging
set logical-systems EDGE-1 interfaces xe-1/0/0 unit 0 vlan-id 2500
set logical-systems EDGE-1 interfaces xe-1/0/0 unit 0 family inet address 1.1.1.2/24 vrrp-group 4 virtual-address 1.1.1.1
set logical-systems EDGE-1 interfaces xe-1/0/0 unit 0 family inet address 1.1.1.2/24 vrrp-group 4 priority 110
set logical-systems EDGE-1 interfaces xe-1/0/0 unit 0 family inet address 1.1.1.2/24 vrrp-group 4 preempt
set logical-systems EDGE-1 interfaces xe-1/0/0 unit 0 family inet address 1.1.1.2/24 vrrp-group 4 accept-data

set interfaces xe-1/1/1 vlan-tagging
set logical-systems EDGE-2 interfaces xe-1/1/1 unit 0 vlan-id 2500
set logical-systems EDGE-2 interfaces xe-1/1/1 unit 0 family inet address 1.1.1.3/24 vrrp-group 4 virtual-address 1.1.1.1
set logical-systems EDGE-2 interfaces xe-1/1/1 unit 0 family inet address 1.1.1.3/24 vrrp-group 4 priority 110
set logical-systems EDGE-2 interfaces xe-1/1/1 unit 0 family inet address 1.1.1.3/24 vrrp-group 4 preempt
set logical-systems EDGE-2 interfaces xe-1/1/1 unit 0 family inet address 1.1.1.3/24 vrrp-group 4 accept-data

 

Thanks,
Pradeep
Please Mark My Solution Accepted if it Helped, Kudos are Appreciated too!!!

 

Hi pradkm,

Getting error:

 

xpaul@H1-EDGE-re0# set logical-systems EDGE-2 interfaces xe-1/1/1 vlan-tagging
^
syntax error.

 

 

HI Xavier,

As already corrected, use " set interfaces xe-1/0/0 vlan-tagging" only for the vlan-tagging configuration, Rest under Logical system hierarchy.

Thanks,
Pradeep,

vlan-tagging should be enabled under root logical system. Not under EDGE-2 logical system. Remaining interface configuration should be under EDGE-2 logical system

 

set interfaces xe-1/1/1 vlan-tagging

set logical-systems EDGE-2 interfaces xe-1/1/1 unit 0 vlan-id 2500
set logical-systems EDGE-2 interfaces xe-1/1/1 unit 0 family inet address 1.1.1.3/24 vrrp-group 4 virtual-address 1.1.1.1
set logical-systems EDGE-2 interfaces xe-1/1/1 unit 0 family inet address 1.1.1.3/24 vrrp-group 4 priority 150
set logical-systems EDGE-2 interfaces xe-1/1/1 unit 0 family inet address 1.1.1.3/24 vrrp-group 4 preempt
set logical-systems EDGE-2 interfaces xe-1/1/1 unit 0 family inet address 1.1.1.3/24 vrrp-group 4 accept-data

 

Hi xavierpaul,

 

Nellikka's observations are correct. You need to have the interface vlan-id assignment in the logical-system EDGE-2, but the vlan-tagging config has to be globally. Please see the output below from a MX, I am using xe-5/1/1 in my case :

tks,

Abhishek

In fact you can go for a routing-instance type virtual-router and put the interface in that routing instance to save yourself from this trouble. All the configuartions for the interface will be globally on the interface.

 

tks,

Abhishek

Thanks Nelikka, abhisek. It works.

Good to know, please accept as solution. 🙂

 

Did you also tryout the routing-instance type virtual router.

 

tks,

Abhishek

Examples have been given by other experts. Here's the rule. 

1. Everything for physical interface, put in global instance 

2. Everything for logical interface, (after unit x), put in logical interface
