Once connectivity and MPLS configuration are verified, the next step is to enable TE and configure IGP for MPLS
TE support.

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
interface GigabitEthernet0/1/0
ip rsvp bandwidth 30000
