Passing MPLS Traffic Between Routing Instance and Inet.0

3 weeks ago

Hi

I want to create two OSPF domains on My Juniper MX960. For this reason I created one Routing-Instance with Type virtual-router. The first thing I observed is I cannot enable protocol MPLS on Interfaces inside of Routing-Instance.. But I can enable LDP on those Interfaces. Another observed case is When I redistribute routes from Routing-Instance to Intet.0, Inet.3 will not received learned labels from the Routing-Instance. 

I test this on Live Device and VMX and got the same result.

Is there any solution for this case? Or it just simply means I must not create separate OSPF Domains..

Thank you

This is expected. Please use instance-type "no-forwarding" for separating OSPF domains in JUNOS if You so desire, but separate IGP domains is not a best practice to put it mildly.

The latter. You could use OSPF multitopology https://kb.juniper.net/library/CUSTOMERSERVICE/technotes/2000308-en.pdf if You are brave but almost everything in networking can be achieved without separating IGP into isolated domains.

This is also true about OSPF NSSA and stub areas, BTW.

Hello,

Can you help understand why you want to create a separate OSPF domain?

One solution is to use logical system on your router. From routing perspective this would be as if it is a separate router and would help you to isolate your domain.

Logical-system supports OSPF and MPLS. Below is a link for configuring P2MP RSVP in logical system which you can use as a reference for configuring P2P RSVP LSP as well.
