Establishing a Static LSP
Establishing a Static LSP
Context
Static LSPs and static Constraint-based Routed LSPs (CR-LSPs)
share the same label space (16-1023). Note that the value of the outgoing
label of the previous node is equal to the value of the incoming label
of the next node.
Perform the following operations on the ingress,
transit, and egress nodes of the static LSP. Figure 3-2 shows planned
labels.
Figure 3-2 Networking of establishing a static LSP
The local node is configured as the ingress node of a specified
LSP.
You are advised to set up a static LSP by specifying a next
hop. Ensure that the local routing table contains the route entries,
including the destination IP address and the next hop IP addresses
of the LSP to be set up.
If an Ethernet interface is used as
an outbound interface of an LSP, the nexthopnext-hop-address parameter must be configured.
As shown in Figure 3-2, the LSP name
is LSP1, destination address is 3.3.3.9/32, next hop address is 172.16.1.2,
outbound interface is Vlanif100, and outgoing label is 100.
The local node is configured as the transit node of a specified
LSP.
You are advised to set up a static LSP by specifying a next
hop address. In addition, ensure that the local routing table contains
the route entries, including the destination IP address and the next
hop IP address of the LSP to be set up.
If an Ethernet interface
is used as an outbound interface of an LSP, the nexthopnext-hop-address parameter must be configured.
As shown in Figure 3-2, the LSP name
is LSP1, the inbound interface is Vlanif100, incoming label is 100, next
hop address is 172.20.1.2, outbound interface is Vlanif200,
and outgoing label is 200.
Configure the egress node.

The local node is configured as the egress node of a specified
LSP.
As shown in Figure 3-2, the LSP name
is LSP1, the inbound interface is Vlanif200, and incoming label is 200.
