NOTE: Note that unified ISSU is supported only by the MICs listed in
Table 18 on page
NOTE: Consider the following guidelines before performing a unified ISSU
on an MX Series router with ATM interfaces at scale:
The PPP keepalive interval must be 10 seconds or greater. PPP requires
three keepalives to fail before it brings down the session. Thirty seconds
(ten seconds multiplied by three) provides a safe margin to maintain PPP
sessions across the unified ISSU in case of any traffic loss during the
operation. Configure the interval with the

The OAM F5 loopback cell period must be 20 seconds or greater to maintain
ATM connectivity across the unified ISSU. Configure the interval with the
statement at the

Unified ISSU Limitations on MX Series Routers
Unified ISSU is currently not supported when clock synchronization is configured for
Synchronous Ethernet, Precision Time Protocol (PTP), and hybrid mode on MX80 routers
and on the MICs and MPCEs on MX240, MX480, and MX960 routers.
