Creating An Mpls-Te Tunnel - Cisco NCS 5500 Series Configuration Manual

Configuring MPLS-TE
Example
This example enables MPLS-TE on a node and then specifies the interface that is part of the MPLS-TE. Here,
OSPF is used as the IGP extension protocol for information distribution.
RP/0/RP0/CPU0:router # configure
RP/0/RP0/CPU0:router(config)# mpls traffic-eng
RP/0/RP0/CPU0:router(config-mpls-te)# interface HundredGigabitEthernet 0/0/0/3
RP/0/RP0/CPU0:router(config)# router ospf area 1
RP/0/RP0/CPU0:router(config-ospf)# area 0
RP/0/RP0/CPU0:router(config-ospf-ar)# mpls traffic-eng
RP/0/RP0/CPU0:router(config-ospf-ar)# interface HundredGigabitEthernet 0/0/0/3
RP/0/RP0/CPU0:router(config-ospf-ar-if)# exit
RP/0/RP0/CPU0:router(config-ospf)# mpls traffic-eng router-id 192.168.70.1
RP/0/RP0/CPU0:router(config)# commit
Example
This example enables MPLS-TE on a node and then specifies the interface that is part of the MPLS-TE. Here,
IS-IS is used as the IGP extension protocol for information distribution.
RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# mpls traffic-eng
RP/0/RP0/CPU0:router(config-mpls-te)# interface HundredGigabitEthernet 0/0/0/3
RP/0/RP0/CPU0:router(config)# router isis 1
RP/0/RP0/CPU0:router(config-isis)# net 47.0001.0000.0000.0002.00
RP/0/RP0/CPU0:router(config-isis)# address-family ipv4 unicast
RP/0/RP0/CPU0:router(config-isis-af)# metric-style wide
RP/0/RP0/CPU0:router(config-isis-af)# mpls traffic-eng level 1
RP/0/RP0/CPU0:router(config-isis-af)# exit
RP/0/RP0/CPU0:router(config-isis)# interface HundredGigabitEthernet 0/0/0/3
RP/0/RP0/CPU0:router(config-isis-if)# exit
RP/0/RP0/CPU0:router(config)# commit

Creating an MPLS-TE Tunnel

Creating an MPLS-TE tunnel is a process of customizing the traffic engineering to fit your network topology.
The MPLS-TE tunnel is created at the headend router. You need to specify the destination and path of the TE
LSP.
To steer traffic through the tunnel, you can use the following ways:
• Static Routing
• Autoroute Announce
• Forwarding Adjacency
Before You Begin
The following prerequisites are required to create an MPLS-TE tunnel:
• You must have a router ID for the neighboring router.
