Application Scenario
A company has five offices, office A through office E, which are connected with one another
through networks. It is required that data from office A to office D must pass through the device
(Router E) in office E. Assume that the routers are reachable to each other after being configured
with IS-IS or OSPF and are properly configured with basic MPLS and MPLS TE capabilities, as
shown in the following figure:
•
Router A: LSR ID address is 1.1.1.1/32; address of Ethernet 1/0 is 2.1.1.1/24.
•
Router B: LSR ID address is 2.2.2.2/32; address of Ethernet 1/0 is 2.1.1.2/24; address of
Ethernet 1/1 is 3.2.1.1/24; address of POS 5/0 is 5.2.1.1/24.
•
Router C: LSR ID address is 3.3.3.3/32; address of Ethernet 1/0 is 4.2.1.1/24; address of
Ethernet 1/1 is 3.2.1.2/24; address of POS 5/0 is 6.2.1.1/24.
•
Router D: LSR ID address is 4.4.4.4/32; address of Ethernet 1/0 is 4.2.1.2/24.
•
Router E: LSR ID address is 5.5.5.5/32; address of POS 5/0 is 5.2.1.2/24; address of POS
5/1 is 6.2.1.2/24.
Scenario Analysis
Configuring an explicit path is to force a tunnel to go through the specified nodes. For example,
in the above networking, for tunnel A from Router A to Router D to pass through Router E, you
need to configure an explicit path that goes through Router E, and then apply the path to tunnel
A. In this way, the tunnel path is Router A -> Router B -> Router E -> Router C -> Router D.
