Deactivating High Availability; Guidelines For Setting The Ip Interface Priority - Juniper SERVICE AVAILABILITY - CONFIGURATION GUIDE V 11.1.X Configuration Manual

Deactivating High Availability

The switch route processor (SRP) module can operate in one of the two redundancy
modes file system synchronization and high availability. When you disable high
availability, the router uses file system synchronization mode which is the default
behavior mode for E Series routers that use redundant SRPs. The router synchronizes
the contents of the NVS (nonvolatile storage) in the primary and standby SRP modules.
To disable high availability support:

Guidelines for Setting the IP Interface Priority

During the warm restart after an SRP switchover, IP and IPv6 interfaces are replayed
from NVS and from mirrored storage. High-priority IP and IPv6 interfaces are replayed
first, followed by static routes, and then by low-priority IP and IPv6 interfaces. This
scheme enables static routes that are dependent on high-priority interfaces to be
resolved and routing protocols to exchange information with peers over high-priority
interfaces before the low-priority interfaces are replayed.
You can designate an IP or IPv6 interface as high priority either implicitly or explicitly:
From Global Configuration mode, launch Redundancy Configuration mode.
host1(config)#redundancy
In Redundancy Configuration mode, you can disable high availability by doing
one of the following:
Specify file system synchronization mode as the redundancy mode.
host1(config-redundancy)#mode file-system-synchronization
Specify the no version to disable high availability.
host1(config-redundancy)#no mode

Implicit designation Configure an IGP or PIM protocol on the interface.
Explicit designation Issue the ip initial-sequence-preference 1 command on
the IP subinterface, or the ipv6 initial-sequence-preference 1 command on the
IPv6 subinterface.
