Once connectivity and MPLS configuration are verified, the next step is to enable TE and configure IGP for MPLS
TE support.
mpls traffic-eng tunnels ! Enable MPLS TE globally and under the
interfaces.
interface GigabitEthernet0/1/1
mpls traffic-eng tunnels
interface GigabitEthernet0/1/0
mpls traffic-eng tunnels
router ospf 100 ! Configure IGP for TE support
mpls traffic-eng router-id Loopback10 ! Specify TE router ID
mpls traffic-eng area 0 ! Enable TE in area 0
Next, specify the bandwidth can be used for traffic engineering. This is the total bandwidth which can be used for
TE under the configured interface. The bandwidth can be lower or higher than actual bandwidth and care should be
taken to make sure other traffic has enough bandwidth. The following command allocates 40M bandwidth under
interface gig0/1/1 and 30M under gi0/1/0 for traffic engineering.
interface GigabitEthernet0/1/1
ip rsvp bandwidth 40000 ! Reserved bandwidth in kbps
interface GigabitEthernet0/1/0
ip rsvp bandwidth 30000 ! Reserved 30M under another interface
