Hi,
I'm currently studdy for my first Junos certification exam. I would like to know deep knowledge required for the exam. Actually I'm trying to do some retribution of routes between these VRFs and it's not working as expected. I would like to know if that kind of topic is part of the first Junos exam. Personnally I find knowlege of VRF concept a little complicated for a first level of exam but it is listed as an exam topic. For me understand VRF include to be able to leak some routes between these VRFs/virtual-router, but I could be wrong.
Here my lab setup see: (I used Juniper vLab IS-IS -l1_L2 Multi-area topologie) I have erased all routers configuration and applied the attached router configuration to this case.
On Router vmx4 I have my 2 virtual-router working fine. I'm able to leak connected route from inet0 to ri-TEACHER VRF. But I would like to have the, I also able to filter the only 10.0.0.0/8 to be leak from the default routing table to ri-TEACHER virtual-router.
Now I'm trying to have route leaking from ri-TEACHER to default rounting instance inet0.
In vritual-router ri-TEAChER I define Lo0.1 and configure 192.168.1.1/24 IP address.
In the default routing instance the network the interface Ge-0/0/2 is configured with 10.1.0.1/24. I also defined static route to 10.0.0.0/8 next-hop 10.1.0.2.
Form up this everything is fine, my 2 virtual-router are completely isolated from each other.
Now I'm trying to make ri-TEACHER can communicated with the rest of the network, to do this I have to make some route leaking between the 2 virtuals ribs ri-TEARCHER.inet.0 and inet.0.
Using rib-group I succefully imported 10.0.0.0/8 next-hop 10.1.0.2 into ri-TEACHER rib. (I'm not sure this is correct, since the 10.1.02 is in fact not reachable from ri-TEACHER.inet.0 but from inet.0 only)
When I tri to do the same thing on the reverse side I don't have any next hop to specified, so I understand that I can't makes route leaking this way.
I found the command "set routing-option static route 192.168.0.0/26 next-table ri-TEACHER.inet.0" to make sense I should do the same on the other side ""set routing-instance ri-TEACHER routing-option static route 10.0.0.0/8 next-table inet.0"
But the router refuse to commit due of the possibility of routing loop. What I should do to accomplished my gold ?
