The Junos OS implementation of MPLS on EX Series switches provides path protection
as a mechanism for protecting against label switched path (LSP) failures. Path protection
reduces the time required to recalculate a route in case of a failure within the MPLS
tunnel. You configure path protection on the ingress provider edge switch in your MPLS
network. You do not configure the egress provider edge switch or the provider switches
for path protection. You can explicitly specify which provider switches are used for the
primary and secondary paths, or you can let the software calculate the paths
automatically.
Before you configure path protection, be sure you have:
Configured an ingress provider edge switch and an egress provider edge switch. See
Configuring MPLS on Provider Edge Switches (CLI Procedure).
Configured at least one provider (transit) switch. See "Configuring MPLS on Provider
Switches (CLI Procedure)" on page 3686.
Verified the configuration of your MPLS network. See "Verifying That MPLS Is Working
Correctly" on page 3699.
