Sample Output from the show mpls forwarding-table Command
In the following example, output information linking the MPLS label with prefixes is displayed using the show mpls forwarding-tablecommand. If the 6PE feature is configured, the labels are aggregated because there are several prefixes for one local label, and the prefix column contains "IPv6" instead of a target prefix.

Sample Output from the show bgp ipv6 Command
In the following example, output information about the top of the stack label with label switching information is displayed using the show bgp ipv6command with the labels keyword:

Sample Output from the show ipv6 cef Command
In the following example, output information about labels from the Cisco Express Forwarding table is displayed using the show ipv6 cefcommand with an IPv6 prefix:
Router# show ipv6 cef 2001:DB8:DDDD::/64

Sample Output from the show ipv6 route Command
In the following example, output information from the IPv6 routing table is displayed using the show ipv6 routecommand. The output shows the IPv6 MPLS virtual interface as the output interface of IPv6 routes forwarded across the MPLS cloud. This example shows output from the 6PE1 router.
The 6PE2 router has advertised the IPv6 prefix of 2001:DB8:dddd::/48 configured for the CE2 router and the next-hop address is the IPv4-compatible IPv6 address ::ffff:192.168.99.70, where 192.168.99.70 is the IPv4 address of the 6PE2 router.
