Configuring MPLS TE

Command Reference

Command	Description
Router(config)#mpls traffic-eng tunnels	Configures TE support on router in the global configuration mode.
Router(config-if)#mpls traffic-eng tunnels	Configures MPLS TE support per interface.
Router(config-if)# ip rsvp bandwidth {reservable bandwidth 1-10000000 kbps} {maximum reservable bandwidth per flow 1-1000000 kbps}	Configures RSVP bandwidth on the interface-reserved bandwidth with the largest reservable bandwidth/flow.
Router(config)#interface tunnel {number}	Configures tunnel interface.
Router(config-if)#ip unnumbered loopback {number}	Configures the loopback interface IP address to be associated with the tunnel interface under tunnel interface configuration.
Router(config-if)#tunnel mode mpls traffic-eng	Configures the tunnel mode to be an MPLS traffic-engineered tunnel.
Router(config-if)#tunnel destination {IP address of remote loopback}	Configures the MPLS traffic-engineered tunnel's destination or end-point.
Router(config-if)#tunnel mpls traffic-eng path-option {priority} dynamic [bandwidth {override bandwidth config value} | attributes {lsp attribute list name} | lockdown]	Configures the LSP path setup to be done by IGP and CSPF (dynamic LSP tunnel creation). The tunnels can be configured with the associated priority and attributes.
Router(config)# ip explicit-path name {name} enable or Router(config)# ip explicit-path identifier {number} enable	Configures an explicit path to be associated with a TE tunnel.
Router(cfg-ip-expl-path)#next-address {ip-address} Router(cfg-ip-expl-path)#exit	Configures the IP next-hop addresses for the explicit MPLS traffic engineered tunnel.
Router(config-if)#tunnel mpls traffic-eng priority {setup priority-value} {hold-priority value}	Defines the priority of the tunnel (used in load balancing).
Router(config-if)#tunnel mpls traffic-eng autoroute announce	Configures tunnel interface to be announced into IGP routing table (configured under tunnel interface configuration).
Router(config-router)#mpls traffic-eng area number	Enables OSPF for TE (under router OSPF configuration).
Router(config-router)#mpls traffic-eng router-id interface number	Configures the router ID for the TE process under OSPF or IS-IS.
Router(config-router)#mpls traffic-eng level [1 | 2]	Configures IS-IS Level1/Level2 domains for TE.
Router(config-router)#metric-style wide	Configures IS-IS to accept and use enhanced TLVs (wide metrics).
Router(config-if)# tunnel mpls traffic-eng fast-reroute	Enables the MPLS tunnel for FRR protection.
Router(config-if)# mpls traffic-eng backup-path tunnel {interface-number}	Configures the backup tunnel to be used during interface failure.
