TOTAL: 2 session(s) Found.
Step 3 Configure IS-IS TE.
# Configure PE1.
[PE1] isis 1
[PE1-isis-1] cost-style wide
[PE1-isis-1] traffic-eng level-2
[PE1-isis-1] quit
# The configuration procedures of P, PE2, and PE3 are similar to the configuration procedure
of PE1.
NOTE
When IS-IS TE is configured on only the local end, the session set up on the local end turns Down. When
IS-IS TE is configured on the remote end, the LDP session becomes Up again.
Step 4 Configure the explicit path of MPLS TE.
# You can manually specify a path for MPLS TE, that is, configure an explicit path for MPLS
TE. Take the configuration of explicit path on PE1 for example.
# Configure PE1.
[PE1] explicit-path PE1toPE2
[PE1-explicit-path-PE1toPE2] next hop 100.1.1.2
[PE1-explicit-path-PE1toPE2] next hop 100.2.1.2
[PE1-explicit-path-PE1toPE2] next hop 2.2.2.9
[PE1-explicit-path-PE1toPE2] quit
[PE1] explicit-path PE1toPE3
[PE1-explicit-path-PE1toPE3] next hop 100.1.1.2
[PE1-explicit-path-PE1toPE3] next hop 100.3.1.2
[PE1-explicit-path-PE1toPE3] next hop 3.3.3.9
[PE1-explicit-path-PE1toPE3] quit
Step 5 Configure the MPLS TE tunnel.
NOTE
An MPLS TE tunnel is unidirectional. To guarantee bidirectional QoS on the TE tunnel, you must configure
an MPLS TE tunnel on PEs.
# Create two tunnel interfaces on PE1; create a tunnel interface on each of PE2 and PE3.
# Configure PE1.
[PE1] interface tunnel 1/0/0
[PE1-Tunnel1/0/0] ip address unnumbered interface loopback 1
[PE1-Tunnel1/0/0] tunnel-protocol mpls te
[PE1-Tunnel1/0/0] destination 2.2.2.9
[PE1-Tunnel1/0/0] mpls te tunnel-id 100
[PE1-Tunnel1/0/0] mpls te signal-protocol rsvp-te
[PE1-Tunnel1/0/0] mpls te path explicit-path PE1toPE2
[PE1-Tunnel1/0/0] mpls te commit
[PE1-Tunnel1/0/0] quit
[PE1] interface tunnel 2/0/0
[PE1-Tunnel2/0/0] ip address unnumbered interface loopback 1
[PE1-Tunnel2/0/0] tunnel-protocol mpls te
[PE1-Tunnel2/0/0] destination 3.3.3.9
[PE1-Tunnel2/0/0] mpls te tunnel-id 200
[PE1-Tunnel2/0/0] mpls te signal-protocol rsvp-te
[PE1-Tunnel2/0/0] mpls te path explicit-path PE1toPE3
