Create a static LSP from Switch A to Switch C
# Configure the LSP ingress, Switch A.
[SwitchA] static-lsp ingress AtoC destination 3.3.3.9 32 nexthop 10.1.1.2 out-label 30
# Configure the LSP transit node, Switch B.
[SwitchB] static-lsp transit AtoC incoming-interface vlan-interface 2 in-label 30 nexthop
20.1.1.2 out-label 50
# Configure the LSP egress, Switch C.
[SwitchC] static-lsp egress AtoC incoming-interface vlan-interface 3 in-label 50
Create a static LSP from Switch C to Switch A
# Configure the LSP ingress, Switch C.
[SwitchC] static-lsp ingress CtoA destination 1.1.1.9 32 nexthop 20.1.1.1 out-label 40
# Configure the LSP transit node, Switch B.
[SwitchB] static-lsp transit CtoA incoming-interface vlan-interface 3 in-label 40 nexthop
10.1.1.1 out-label 70
# Configure the LSP egress, Switch A.
[SwitchA] static-lsp egress CtoA incoming-interface vlan-interface 2 in-label 70
Verify the configuration
# After the above configurations, execute the display mpls static-lsp command on each switch to
view the static LSP information. The following takes Switch A as an example:
[SwitchA] display mpls static-lsp
total statics-lsp : 2
Name FEC I/O Label I/O If State
AtoC 3.3.3.9/32 NULL/30 -/Vlan2 Up
CtoA -/- 70/NULL Vlan2/- Up
# On Switch A, check the connectivity of the LSP from Switch A to Switch C.
