Known Affected Releases

20.1

Description (partial)

Symptom:
No matter which Interface on Service Side VPN is used, the result is the same when trying to run a Simulate flow for tunnel and Service Path. Below, the error that we got:

Failed to run tunnel path
Interface GigabitEthernet0/0/2 not up

Failed to run service path
Interface GigabitEthernet0/0/2 not up

Configuration:
VPN -> 10 (Service side)
Source Interface -> GigabitEthernet0/0/2
Source IP -> ************* (I hide intentionally the customer IPs)
Destination IP -> ************** (I hide intentionally the customer IPs)
Protocol -> 1

------------------------------------------
it's worth saying that:
1.- Interface is up and running
VPN 10 - Interface GigabitEthernet0/0/2 - Admin Status UP - Operational Status UP

2.- There is full IP connectivity back and forth 
Output:
