Egress protection LSPs—If there is a link or node failure in the core network, a protection
mechanism such as MPLS fast reroute can be triggered on the transport LSPs between
the PE routers to repair the connection within tens of milliseconds. An egress protection
LSP addresses the problem of when a link failure occurs at the edge of the network
(for example, a link failure between a PE router and a CE device).
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
statement at the
context-identifier

hierarchy levels.

circuit and also configures the protector Layer 2 circuit itself at the
