Page 86: Graceful Restart For Aggregate And Static Routes
High Availability Feature Guide for EX9200 Switches Graceful restart works similarly for routing protocols and MPLS protocols and combines components of these protocol types to enable graceful restart in VPNs. The main benefits of graceful restart are uninterrupted packet forwarding and temporary suppression of all routing protocol updates.

Page 139: Network Failures
To minimize network traffic, VRRP is designed in such a way that only the router that is acting as the master sends out VRRP advertisements at any given point in time. The backup routers do not send any advertisement until and unless they take over mastership. Copyright © 2017, Juniper Networks, Inc.
Page 140: Figure 8: Basic Vrrp
High Availability Feature Guide for EX9200 Switches VRRP for IPv6 provides a much faster switchover to an alternate default router than IPv6 neighbor discovery procedures. Typical deployments use only one backup router. Figure 8 on page 120 illustrates a basic VRRP topology. In this example, Routers A, B, and C are running VRRP and together make up a virtual router.

High Availability Feature Guide for EX9200 Switches NOTE: VRRP (for IPv6) on routers that use Junos OS Release 12.2 and later releases does not interoperate with VRRP (for IPv6) on routers with earlier Junos OS releases because of the differences in VRRP checksum calculations.
Page 143: Upgrading From Vrrpv2 To Vrrpv3
During the transition period, both VRRPv2 and VRRPv3 operate in the network. Changing VRRP versions restarts the state machine for all VRRP groups. VRRPv3 (for IPv4) routers default to the backup state when they get VRRPv2 (for IPv4) advertisement packets. Copyright © 2017, Juniper Networks, Inc.
Page 144: Table 7: Vrrpv2 To Vrrpv3 Transition Steps And Events
High Availability Feature Guide for EX9200 Switches VRRPv2 (for IPv4) packets are always given the highest priority. Checksum differences between VRRPv2 and VRRPv3 (for IPv6) can create multiple master routers.
