5. Configure an MPLS TE tunnel on Switch A:
# Configure MPLS TE tunnel interface Tunnel 0.
[SwitchA] interface tunnel 0 mode mpls-te
[SwitchA-Tunnel0] ip address 6.1.1.1 255.255.255.0
# Specify the tunnel destination address as the LSR ID of Switch C.
[SwitchA-Tunnel0] destination 3.3.3.3
# Configure MPLS TE to use a static CRLSP to establish the tunnel.
[SwitchA-Tunnel0] mpls te signaling static
[SwitchA-Tunnel0] quit
6. Create a static CRLSP:
# Configure Switch A as the ingress node of the static CRLSP, and specify the next hop
address as 2.1.1.2, outgoing label as 20, and bandwidth for the tunnel as 2000 kbps.
[SwitchA] static-cr-lsp ingress static-cr-lsp-1 nexthop 2.1.1.2 out-label 20
bandwidth 2000
# On Switch A, configure tunnel 0 to reference the static CRLSP static-cr-lsp-1.
[SwitchA] interface Tunnel0
[SwitchA-Tunnel0] mpls te static-cr-lsp static-cr-lsp-1
[SwitchA-Tunnel0] quit
# Configure Switch B as the transit node of the static CRLSP, and specify the incoming label as
20, next hop address as 3.2.1.2, outgoing label as 30, and bandwidth for the tunnel as 2000
kbps.
[SwitchB] static-cr-lsp transit static-cr-lsp-1 in-label 20 nexthop 3.2.1.2 out-label
30 bandwidth 2000
# Configure Switch C as the egress node of the static CRLSP, and specify the incoming label as
30.

7. Configure a static route on Switch A to direct traffic destined for subnet 3.2.1.0/24 to MPLS TE
tunnel 0.
[SwitchA] ip route-static 3.2.1.2 24 tunnel 0 preference 1
Verifying the configuration
# Execute the display interface tunnel command on Switch A. The output shows that the tunnel
interface is up.
[SwitchA] display interface tunnel

Current state: UP
Line protocol state: UP
