Guidelines for Upgrading Software

for the software on each SRP module.
The most efficient way to upgrade the software is to ensure that the standby SRP
module is armed with the new release and then reload the standby SRP module.
This reload occurs automatically after you download and arm a new release onto the

Setting the IP Interface Priority

Delete the IP or IPv6 interface.
Remove all high-priority configuration from the IP or IPv6 interface, then reload
the router.

From Subinterface Configuration mode, explicitly configure the IPv4 interface
as high-priority:
host1(config-subif)#ip initial-sequence-preference 1
From Subinterface Configuration mode, explicitly configure the IPv6 interface
as low-priority:
host1(config-subif)#ipv6 initial-sequence-preference 0
