JNCIP-ENT EVPN Practice Question
You are troubleshooting a scenario where an MX Series router running an EVPN-VXLAN instance receives Type-2 routes from a remote PE, but the local data plane fails to install the forwarding entries because of a mismatch in encapsulation types. Where is the encapsulation type for VXLAN defined within a Junos EVPN instance?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
routing-instances <name> instance-type evpn; ... encapsulation vxlan;
In Junos OS, the encapsulation for the routing instance or switch options is defined using the 'encapsulation vxlan' statement under the routing-instance or switch-options hierarchy.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
protocols bgp group <name> family evpn encapsulation vxlan
Why it's wrong here
BGP family configuration specifies the address family, but data-plane encapsulation is defined under the routing instance or switch options.
- ✗
interfaces lo0.0 family vxlan
Why it's wrong here
Loopback interfaces do not take a family vxlan configuration.
- ✓
routing-instances <name> instance-type evpn; ... encapsulation vxlan;
Why this is correct
Encapsulation vxlan is configured directly inside the routing instance or switch options block.
- ✗
bridge-domains <name> vni <id> encapsulation mpls
Why it's wrong here
This would enforce MPLS encapsulation instead of VXLAN, causing a mismatch if VXLAN is expected.
