Figure 63: VSU Tunnel Persistence
Figure 64, illustrates tunnel persistence between SGs and remote users (RUser). The addition
of SG
D
to VPN
2
(SG
A
, SG
C
, SG
D
, and Remote User) interrupts tunnel persistence in VPN
2
,
thus breaking the remote connection. Once the configuration update is complete, the remote
connection will be restored. Because modifications have not been made in VPN
1
(SG
A
and
SG
B
) and VPN
3
(SG
B
and SG
D
), tunnels remain persistent.
