Hello!
There is a problem that I just can’t figure out 🙂
Juniper MX80 has three vlan 10,20,30 on tagged port ge-1/1/8 with vlan-per user clients which use static IP addressing through unnumbered.
Here is a part of a working configuration:
Loopback interface
interfaces lo0
unit 0 {
family inet {
address 10.20.30.1/32;
}
}
Access interfaces
interfaces ge-1/1/8 {
flexible-vlan-tagging;
encapsulation flexible-ethernet-services;
unit 20 {
vlan-id 20
family inet {
unnumbered-address lo0.0;
}
unit 30 {
vlan-id 30
family inet {
unnumbered-address lo0.0;
}
}
Route to client
routing-options
static {
route 10.20.30.2/32 {
qualified-next-hop ge-1/1/8.20;
}
route 10.20.30.3/32 {
qualified-next-hop ge-1/1/8.30;
}
}
We run a STP ring to theese clients to improve connectivity and now that vlans can be reached out via ge-1/1/7 or ge-1/1/8 tagged ports. I decided to do this through the bridge-domain and irb interface, but there is a restriction that that does not allow setting an unnumbered address on the irb interface. For now I decided to put a copper patch or logical-tunnel between the ports in the router to collect these vlan at one point and terminate them with unnumbered.
But this scheme seems to be wrong.
Is it a technical limitation of the architecture?
Any other correct way?
Thank you in advance!
