MPLS TE Tunnel Using
RSVP-TE Configuration
Example
ONFIGURATION
On an MPLS TE tunnel configured using a static CR-LSP, traffic is forwarded directly
based on label at the transit nodes and egress node. Therefore, it is normal that
the FEC field in the sample output is empty on Route B and Router C.
7 Create a static route for routing MPLS TE tunnel traffic.
[RouterA] ip route-static 3.3.3.3 32 tunnel 0 preference 1
Perform the display ip routing-table command on Router A. You can find a
static route entry with interface Tunnel0 as the outgoing interface.
Network requirements
Router A, Router B, Router C, and Router D are running IS-IS and all of them
■
are Level-2 routers.
Use RSVP-TE to create a TE tunnel with 2000 kbps of bandwidth from Router A
■
to Router D, ensuring that the maximum bandwidth of each link that the
tunnel traverses is 10000 kbps and the maximum reservable bandwidth is 5000
kbps.
