Routing

hi team,

 

Am trying use EM0 and EM1 interfaces on an MX to link logical systems. am having challenge confugre any other unit apart from unit 0 under EM0 interface. i have configured vlan-tagging under EM0 interface.

 

this is the error i get:

 

Only unit 0 is valid for this interface

root# show interfaces em0
vlan-tagging;
unit 1 {
    vlan-id 10;
    family inet {
        address 10.10.10.1/24;
    }
}

[edit]


root# commit check

[edit interfaces em0]
  'unit 1'
    Only unit 0 is valid for this interface
error: configuration check-out failed

how can i go around this?

 

 

Hello,

 

To connect two logical systems, lt interfaces are used.

em0 is used for Management.

Hi rushi,
Thank you so much for the response.
I would have preferred the lt interface also but I can't see it appearing when I say "sh int terse". The management interface you mentioned is ME0 interface and the one am using is EM0 interface. I have seen the em0 interface been used to interconnect logical systems.

Hello,

 

You will have to configure something like this so that lt interfaces can be seen & configured:

 

set chassis fpc <number> pic <number> tunnel-services bandwidth <value>

 

I have not come across a scenario where em0 is used to interconnect logical systems so far.
