4. Create a static LSP from Switch A to Switch C:
# Configure the LSP ingress, Switch A.
[SwitchA] static-lsp ingress AtoC destination 21.1.1.0 24 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
5. Create a static LSP from Switch C to Switch A:
# Configure the LSP ingress, Switch C.
[SwitchC] static-lsp ingress CtoA destination 11.1.1.0 24 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
6. Verify the configuration:
# Execute the display mpls static-lsp command on each switch to view static LSP information. Take
Switch A as an example:
[SwitchA] display mpls static-lsp
total statics-lsp : 2
Name FEC I/O Label I/O If State
AtoC 21.1.1.0/24 NULL/30 -/Vlan2 Up
CtoA -/- 70/NULL Vlan2/- Up
# On Switch A, test the connectivity of the LSP from Switch A to Switch C.
