Step Command Remarks
6. Create a static CR-LSP on your
router depending on its
location in the network.
• At the ingress:
static-cr-lsp ingress tunnel-name
destination dest-addr { nexthop
next-hop-addr | outgoing-interface
interface-type interface-number } out-label
out-label-value [ bandwidth [ ct0 | ct1 |
ct2 | ct3 ] bandwidth-value ]
• On the transit node:
static-cr-lsp transit tunnel-name
incoming -interface interface-type
interface-number in-label in-label-value
{ nex thop next-hop-addr |
outg oing-interfac e interface-type
interface-number } out-label
out-label-value [ ba ndwidth [ ct0 | ct1 |
ct2 | ct3 ] bandwidth-value ]
• At the egress:
static-cr-lsp egress tunnel-name
incoming-interface interface-type
interface-number in-label in-label-value
[ lsrid ingress-lsr-id tunnel-id tunnel-id ]
[ bandwidth [ ct0 | ct1 | ct2 | ct3 ]
bandwidth-value ]
Use any of the
commands depending
on the location of your
router in the network.
NOTE:
•
The tunnel-name argument specifies the name of the MPLS TE tunnel carried over the static CR-LSP.
• The tunnel-name argument in the static-cr-lsp ingress command is case-sensitive. Suppose you create
a tunnel interface with the interface tunnel 2 command. To specify it for the tunnel-name in the
static-cr-lsp ingress command, you must input its name in the form of Tunnel2. Otherwise, your tunnel
establishment attempt will fail. This restriction however does not apply to transit and egress nodes.
• The next hop address cannot be a local public address when configuring the static CR-LSP on the ingress
or a transit node.
Configuring MPLS TE tunnel with dynamic signaling
protocol
Dynamic signaling protocol can adapt the path of a TE tunnel to network changes and implement
redundancy, FRR, and other advanced features.
The following describes how to create an MPLS TE tunnel with a dynamic signaling protocol:
• Configure MPLS TE properties for links and advertise them through IGP TE extension to form a TEDB.
• Configure tunnel constraints.
• Use the CSPF algorithm to calculate a preferred path based on the TEDB and tunnel constraints.
• Establish the path by using the signaling protocol RSVP-TE or CR-LDP.
