Example: Configuring Backup Selection Policy for the OSPF or OSPF3 Protocol
This example shows how to configure the backup selection policy for the OSPF or OSPF3 protocol, which enables you to select a loop-free alternate (LFA) in the network.
When you enable backup selection policies, Junos OS allows selection of LFA based on the policy rules and attributes of the links and nodes in the network. These attributes are admin-group, srlg, bandwidth, protection-type, metric, and node.
Requirements
This example uses the following hardware and software components:
Eight routers that can be a combination of M Series Multiservice Edge Routers, MX Series 5G Universal Routing Platforms, PTX Series Packet Transport Routers, and T Series Core Routers
Junos OS Release 15.1 or later running on all devices
Before you begin:
Configure the device interfaces.
Configure OSPF.
Overview
In Junos OS, the default loop-free alternative (LFA) selection
algorithm or criteria can be overridden with an LFA policy. These
policies are configured for each destination (IPv4 and IPv6) and a
primary next-hop interface . These backup policies enforce LFA selection
based on admin-group, srlg, bandwidth, protection-type, metric, and
node attributes of the backup path. During backup shortest-path-first
(SPF) computation, each attribute (both node and link) of the backup
path, stored per backup next-hop, is accumulated by IGP. For the routes
created internally by IGP, the attribute set of every backup path
is evaluated against the policy configured for each destination (IPv4
and IPv6) and a primary next-hop interface. The first or the best
backup path is selected and installed as the backup next hop in the
routing table. To configure the backup selection policy, include the backup-selection configuration statement at the [edit
routing-options] hierarchy level. The show backup-selection command displays the configured policies for a given interface and
destination. The display can be filtered against a particular destination,
prefix, interface, or logical systems.
Topology
In this topology shown in Figure 1, the backup selection policy is configured on Device R3.

Configuration
CLI Quick Configuration
To quickly configure this example, copy the
following commands, paste them into a text file, remove any line breaks,
change any details necessary to match your network configuration,
copy and paste the commands into the CLI at the [edit] hierarchy
level, and then enter commit from configuration mode.

Configuring Device R3
Step-by-Step Procedure
The following example requires that you navigate various levels in the configuration hierarchy. For information about navigating the CLI, see Using the CLI Editor in Configuration Mode in the CLI User Guide.
To configure Device R3:
Configure the interfaces.
[edit interfaces] user@R3# set ge-0/0/5 unit 0 family inet address 172.16.50.2/30 user@R3# set ge-0/0/5 unit 0 family inet6 address 2001:db8:50:1:1::2/64 user@R3# set ge-0/0/5 unit 0 family mpls user@R3# set xe-0/3/1 unit 0 family inet address 172.16.75.1/30 user@R3# set xe-0/3/1 unit 0 family inet6 address 2001:db8:75:1:1::1/64 user@R3# set xe-0/3/1 unit 0 family mpls user@R3# set ge-1/0/0 unit 0 family inet address 172.16.80.1/30 user@R3# set ge-1/0/0 unit 0 family inet6 address 2001:db8:80:1:1::1/64 user@R3# set ge-1/0/0 unit 0 family mpls user@R3# set ge-1/0/5 unit 0 family inet address 172.16.200.1/24 user@R3# set ge-1/0/5 unit 0 family inet6 address 2001:db8:200:1:1::1/64 user@R3# set ge-1/0/6 unit 0 family inet address 172.16.85.1/30 user@R3# set ge-1/0/6 unit 0 family inet6 address 2001:db8:85:1:1::1/64 user@R3# set ge-1/0/6 unit 0 family mpls user@R3# set xe-1/3/0 unit 0 family inet address 172.16.90.1/30 user@R3# set xe-1/3/0 unit 0 family inet6 address 2001:db8:90:1:1::1/64 user@R3# set xe-1/3/0 unit 0 family mpls user@R3# set lo0 unit 0 family inet address 172.16.3.3/32 primary user@R3# set lo0 unit 0 family inet6 address 2001:db8::3:3:3:3/128 primary user@R3# set lo0 unit 0 family mpls

Results
From configuration mode, confirm your configuration
by entering the show interfaces, show protocols, show policy-options, and show routing-options commands. If the output does not display the intended configuration,
repeat the instructions in this example to correct the configuration.
