Build MPLS-TE Topology and Tunnels: Example
Build MPLS-TE Topology and Tunnels: Example
The following examples show how to build an OSPF and IS-IS topology:
(OSPF)
...
configure
show mpls traffic-eng topology
show mpls traffic-eng link-management advertisement
!
(IS-IS)
...
configure
!
The following example shows how to configure tunnel interfaces:
interface tunnel-te1
show mpls traffic-eng tunnels
show ipv4 interface brief
show mpls traffic-eng link-management admission-control
!
interface tunnel-te1
ping 192.168.12.52
show mpls traffic autoroute
!
interface tunnel-te1
