I'm trying to deploy MPLS in a lab to study VPLS and TE Tunnels.
This is my scenario (R1 to R7 are RB493AH):
My notebook is connected to R1, and the server to R4.
All routers are in 6.37.5 version. Also, all of them have loopback configured (10.0.0.1 to 10.0.0.7)
OSPF is running perfectly. All paths have cost = 10.
The problem is: when I enable MPLS in all routers, some routers became freezed (R3, R4, R6 and R7) when I try to access them from the notebook.
Example: R3 with MPLS enabled:
I've enabled LDP settings, configured LSR ID and transport address equal to IP of loopback.
All routers have default MTU = 1508.
What I am doing wrong?
