Describes the unified debug condition capability for IPv4 and IPv6 traffic over MPLS packets on Cisco IOS XE Catalyst SD-WAN devices.
A unified debug condition is a troubleshooting capability that
-
adds a debug condition for IPv4 and IPv6 traffic over MPLS packets
-
specifies a filter condition to select the overlay IP address and optionally, the underlay MPLS label with a stack depth, and
-
identifies specific packets that match certain filtering criteria to troubleshoot any issues related to the MPLS traffic.
Unified debug condition process
The matching of IPv4 and IPv6 over MPLS is a three step process:
-
Debugging
-
Specifying the filtering conditions
-
Applying the filer conditions to the devices
In Cisco IOS XE Catalyst SD-WAN devices, the MPLS label is used to represent an IP VRF and is distributed by OMP protocol.
