I have the following scenario:
CCR 2004 with OSPF and MPLS in version 6.48.6, making a point to point for a CRS-317 in version 7.1.3 with VLAN 4090, the Switch is with HardwareOffload and OSPF working perfectly, however, when activating MPLS and LDP I lose the ping to the router that is after the CRS-317, I can't ping on the Loopsback interfaces, only on the interfaces that do Point to Point with this CRS-317.
Remembering that in Switch CRS-317 I can ping the router that has loopback 10.2.0.19 but in no other network I can ping, even having the route at all, and remembering that when disabling LDP the ping returns to normal.
