Installing a SIP
Online insertion and removal (OIR) is supported, enabling you to remove and install SIPs while the
router is operating. OIR is seamless to users on the network, maintains all routing information, and
ensures session preservation.
With OIR, notifying the software or resetting the power is not required. However, you have the
option of using the shutdown command before removing a SIP.
After you reinstall a SIP, the router automatically downloads the necessary software from the route
processor (RP). Next, the router brings online only those interfaces that match the current
configuration and were previously configured as administratively up. You must configure all others
with the configure command.
