MPLS Configuration Traffic Engineering
Constrained Path Selection Configuration Example for IS-IS Traffic Engineering
The following examples shows the configuration of two constrained path LSPs from R1 to R4:
• LSP1 includes the administrative group ‘red’
• LSP2 includes the administrative group ‘green’ and the bandwidth constraint of 8 megabits per
second
IS-IS is the IGP running on all routers in the network. IS-IS MD5 authentication is also configured.
Timesaver Click on the router name (in blue) to see the corresponding configuration.

Note For simplicity, the configurations shown in this section are for unidirectional
LSPs from R1 to R4. In most cases, you would also need to configure LSPs in the
reverse direction, from R4 to R1.
The following is the configuration for R1:
! Create interfaces
interface create ip to-R2 address-netmask 153.1.1.13/16 port gi.2.1
interface add ip lo0 address-netmask 113.113.113.113/32
! Configure IS-IS
ip-router global set router-id 113.113.113.113
ip-router policy redistribute from-proto direct to-proto isis-level-1
ip-router authentication create key-chain test1 key ed301c4c0a9b1171 type primary id 255 ( key is encrypted)
isis add area 53.da05
R5
R4 R3 R2 R1
LSP1 (admin group red)
LSP2 (admin group green, 8 Mbits/sec. bandwidth)
