Chapter 3: Managing Stateful SRP Switchover
Unsupported Notes
– Static and dynamic interfaces, with the
exception of ATM subscribers, are
supported.
In this case, ATM subscribers refers to a
technology on the E Series router where
the ATM layer does authentication (that
is, not PPP or IP subscriber manager).

– During a stateful SRP switchover, the
BFD transmit interval is set to 1000 ms
with a detection multiplier of 3. These
values result in a liveness detection
interval of 3000 ms. This longer interval
helps prevent a BFD timeout during the
switchover. BFD negotiates the interval
with the remote peer before applying the
temporary change. The BFD timers revert
back to the configured values after 15
minutes (the maximum duration for
graceful restart completion).
– Supported for IPv4 only when the
graceful restart extension is enabled.
Does not support graceful restart for
IPv6 address families.
– Static recovery support only.
