MPLS Traffic Engineering Notes
Guys, a super free little resource for MPLS-TE courtesy of Cisco Press. I printed this baby off and carry it with me along with all my summary notes.
PS: Less than 3 weeks to go!
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} enableor
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. |
