Copying Release Files from One Router to Another

When you have copied the release files from a network host to one router, you can
transfer files from that router to other routers on the network. This feature is useful
when:
The procedures for transferring release files from a source router to a destination
router are almost identical to transferring release files from a network host to a router
on the same side of the firewall.
NOTE: You must enable the FTP server on the source router.
To transfer release files from a source router to a destination router, follow the
instructions in "Installing Software When a Firewall Does Not Exist" on page 132,
with the following changes:

Upgrading Systems That Are Operating with Two SRP Modules

Use this procedure when the system contains two SRP modules and is already
operating with an earlier software release. Each SRP module keeps the system
operational while you upgrade the software on the other, so that you can minimize
service interruption.
CAUTION: You must upgrade the software on the redundant SRP module when you
upgrade the software on the primary SRP module. This action prevents the redundant
SRP module from overwriting the new software on the primary SRP module if the
primary SRP module fails and the redundant SRP module takes control.

Copying Release Files from One Router to Another
The other routers are unreachable from the network host but have network
connectivity to the router on which you installed the new software.
The connection between routers is faster than the connection between a router
and the network host to which it is connected.
Substitute the source router for the network host.
Omit the step about copying the release files to the network host.
Copy the file to the system space of the second router from the user space of
the first router.
Be sure to specify the correct software release (.rel) filename for the router you
are using, as described in "Identifying the Software Release File" on page 126.
For example:
host1#copy boston:/outgoing/releases/erx_x-y-z.rel erx_x-y-z.rel
