Engine switchover also supports the unified in-service software upgrade (ISSU) for the
DHCP access model and the PPPoE access model used by subscriber access.
Graceful Routing Engine switchover is supported on most PICs, except for the services
PICs listed in this section. The PIC must be on a supported routing platform running the
appropriate version of Junos OS. For information about FPC types, FPC/PIC compatibility,
and the initial Junos OS Release in which an FPC supported a particular PIC, see the PIC
guide for your router platform.
The following constraints apply to graceful Routing Engine switchover support for services
PICs:
You can include the graceful-switchover
hierarchy level on a router with Adaptive Services, Multiservices, and Tunnel Services
PICs configured on it and successfully commit the configuration. However, all services
on these PICs—except the Layer 2 service packages and extension-provider and SDK
applications on Multiservices PICs—are reset during a switchover.
Graceful Routing Engine switchover is not supported on any Monitoring Services PICs
or Multilink Services PICs. If you include the
hierarchy level on a router with either of these PIC types configured
chassis redundancy]
on it and issue the
commit
Graceful Routing Engine switchover is not supported on Multiservices 400 PICs
configured for monitoring services applications. If you include the
statement, the commit fails.
NOTE: When an unsupported PIC is online, you cannot enable graceful
Routing Engine switchover. If graceful Routing Engine switchover is already
enabled, an unsupported PIC cannot come online.
Release Description
13.2 Starting with Junos OS Release 13.2, when a graceful Routing Engine
switchover occurs, the VRRP state does not change.
