Multiple loopback units

Hi,

In the
http://ww
w.juniper.net/techpubs/software/junos/junos80/swconfig80-vpn
s/html/vpnl3-config32.html#1072419

I can read the following text: For Layer 3 VPNs (VRF routing
instances), you
can configure a logical unit on the loopback interface into
each VRF routing
instance that you have configured on the router. Associating
a VRF routing
instance with a logical unit on the loopback interface
allows you to easily
identify the VRF routing instance.

What I tried to do is:
[edit interfaces lo0 unit 5 family inet]
router# commit
[edit interfaces lo0]
  'unit 5'


I got the following error:
    if_instance: Multiple loopback interfaces not permitted
in master
routing instance
error: configuration check-out failed


How can I configure multiple loopback units, one for each
vrf?

Thank you


Jose Sanchez

Jose,

You also need to assign the "extra" logical
interfaces to the appropriate VR.

For example, in this case, "set routing-instances
<instance> interface
lo0.5" should do the appropriate thing.

You will get that error until you bind the interface to a
routing-instance
eg.

TEST-VPN {
    instance-type vrf;
    interface lo0.5;
    route-distinguisher 10:123;
    vrf-target target:10:123;
}

You have to then place the non-0 unit lo0 interface into a
vrf before
you can commit:

 
[edit]
harryvpn11# show interfaces lo0   
unit 1 {
    family inet {
        address 1.100.1.2/32;
    }
}

[edit]
harryvpn11# show routing-instances 
ce1 {
    instance-type vrf;
    interface lo0.1;
    route-distinguisher 1:1;
    vrf-target target:100:1;
}

[edit]
harryvpn11# commit check 
configuration check succeeds

[edit]
harryvpn11# delete routing-instances ce1 interface lo0.1 

[edit]
harryvpn11# commit check 
[edit interfaces lo0]
  'unit 1'
    if_instance: Multiple loopback interfaces not permitted
in master
routing instance
error: configuration check-out failed

[edit]
harryvpn11# rollback 0
