Juniper JUNOS OS 10.4 - RELEASE NOTES - Page 36

To enable an egress protection LSP, you need to configure the following statements:
•
context-identifier—Specifies an IPv4 address used to define the pair of PE routers
participating in the egress protection LSP. The context identifier is used to assign an
identifier to the protector PE router. The identifier is propagated to the other PE
routers participating in the network, making it possible for the protected egress PE
router to signal the egress protection LSP to the protector PE router. Configure the
context-identifier statement at the [edit protocols l2circuit neighbor neighbor-address
interface interface-name egress-protection protector-pe] and the [edit protocols mpls
egress-protection] hierarchy levels.
•
egress-protection—Configures the protector information for the protected Layer 2
circuit and also configures the protector Layer 2 circuit itself at the [edit protocols
l2circuit] hierarchy level. Configures an LSP as an egress protection LSP at the [edit
protocols mpls label-switched-path lsp-name] hierarchy level. It also configures the
context identifier at the [edit protocols mpls] hierarchy level.
•
protected-l2circuit—Specifies which Layer 2 circuit is to be protected by the egress
protect LSP. This statement includes the following sub-statements: ingress-pe,
egress-pe, and virtual-circuit-id. These sub-statements specify the address of the
PE router at the ingress of the Layer 2 circuit, the address of the PE router at the
egress of the Layer 2 circuit, and the Layer 2 circuit’s identifier respectively. Configure
the protected-l2circuit statement at the [edit protocols l2circuit neighbor address
interface interface-name] hierarchy level.
•
protector-pe—Specify the IPv4 address of the protector PE router. The protector PE
router must have a connection to the same CE device as the protected PE router for
the egress protect LSP to function. This statement includes the following
sub-statements: context-identifier and lsp. The lsp statement specifies the LSP to
be used as the actual egress protection LSP. Configure the protector-pe statement
at the [edit protocols l2circuit neighbor neighbor-address interface interface-name
egress-protection] hierarchy level.

•
Local switching support for the ignore-encapsulation-mismatch statement—The
ignore-encapsulation-mismatch statement has been extended to support local
switching. You can now configure this statement at the [edit protocols l2circuit
local-switching interface interface-name] hierarchy level. This statement allows a Layer
2 circuit to be established even though the encapsulation configured on the CE device
interface does not match the encapsulation configured on the Layer 2 circuit interface.
Local switching allows you to configure a Layer 2 circuit entirely on the local router,
terminating the circuit on a local interface.
