Table 4-5 Default Boot Filenames - Cisco GSR12/60 - 12012 Router -AnyLAN, SONET/SDH Installation And Configuration Manual

Table 4-5 lists the default boot filenames. A boot system configuration command in the
configuration file in NVRAM overrides the default filename created for booting over the
network.
Note If a bootable Cisco IOS software image exists in a Flash memory card installed in
PCMCIA slot 0 or slot 1, the configuration register setting is overridden and the bootable
Cisco IOS software image will be booted instead of the default TFTP-bootable Cisco IOS
software image (cisco2-grp through cisco17-grp on the GRP and cisco2-prp through
cisco17-prp on the PRP).
