Cisco CRS Configuration Guide

This example shows how to configure installing four autoroute destination routes into the RIB along with the
default route:
interface tunnel-te10
autoroute destination 192.168.1.2
autoroute destination 192.168.2.2
autoroute destination 192.168.3.2
autoroute destination 192.168.4.2
Configuring IPv6 Routing Over IPv4 MPLS-TE Tunnels
Perform these steps to configure IPv6 routing over IPv4 MPLS-TE tunnels:
SUMMARY STEPS
1.
configure
2.
interface tunnel-te tunnel-id
3.
ipv4 unnumbered type interface-path-id
4.
ipv6 enable
5.
signalled-bandwidth bandwidth
6.
destination ip-address
7.
Use one of these options:
•
autoroute announce include-ipv6
•
forwarding-adjacency include-ipv6
8.
path-option preference-priority dynamic
9.
Use the commit or end command.
10.
(Optional) show mpls traffic-eng autoroute
