Introduction to MPLS

Hi Rene,

I have a problem with my topology in EVE-NG Emulator. In this lesson before starting configuring MPLS, i saw that the GRE Tunnel doesnt work. Below you can verify that the protocol on interface tunnel 0 is down on PE1 side. Can you help me solve this problem?

PE1 Router:

PE1#sh ip inte brief 
Interface              IP-Address      OK? Method Status                Protocol
FastEthernet0/0        192.168.23.2    YES NVRAM  up                    up      
FastEthernet1/0        192.168.12.2    YES NVRAM  up                    up      
FastEthernet2/0        unassigned      YES NVRAM  administratively down down    
Loopback0              2.2.2.2         YES NVRAM  up                    up      
Tunnel0                192.168.24.2    YES NVRAM  up                    down 

PE2 Router:

PE2#sh ip inte brief 
Interface              IP-Address      OK? Method Status                Protocol
FastEthernet0/0        192.168.34.4    YES manual up                    up      
FastEthernet1/0        192.168.45.4    YES manual up                    up      
FastEthernet2/0        unassigned      YES unset  administratively down down    
Tunnel0                192.168.24.4    YES manual up                    up
