Command History
Usage Guidelines This command is not supported on Cisco 7600 series routers that are configured with a Supervisor
En
gine 2.
If you do not enable tunnel-MPLS recirculation, the IPv4 and IPv4-tunneled packets that need to be
la
beled (for example, the packets that are encapsulated with an MPLS header) will be corrupted when
they are transmitted from the Cisco 7600 series router.
Use the show
erm statistics command to display the Forwarding Information Base (FIB) Ternary
Content Addressable Memory (TCAM) exception status for IPv4, IPv6, and MPLS protocols.
Examples This example shows how to enable the aggregated-label MPLS recirculation:
