To provide uninterrupted service during
an SRP switchover in a scaled
configuration, such as one with 32,000
Martini circuits, set the LDP graceful
restart reconnect time to the maximum
300 seconds and set the LDP graceful
restart recovery timer to the maximum
600 seconds. This requirement is true
for all SRP switchovers, including those
in the context of a unified in-service
software upgrade.
LDP signaling does not support HA for
IPv6.

Following a switchover, the DHCP lease
(that is, time remaining) is recalculated
based on when the lease started. When
the release timer for a client expires, the
client is deleted and the access route is
removed, along with the dynamic
subscriber interface if it was created. If
the client requests a new lease, DHCP
external server resynchronizes with the
new lease time.
