Explanation:

Global Configuration Mode
Prompt: (config)
Enter global configuration mode from executive (EXEC) mode by using the configure command.
Global configuration commands generally apply to the whole system rather than just one protocol
or interface. You can enter all other configuration submodes listed in this section from global
configuration mode.
RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)#
Global Parameter Configuration Mode
Prompt: (config-rpl-gl)
Enter global parameter configuration mode by using the policy-global command in global
configuration mode.
In global parameter configuration mode, you can create or modify a global policy by entering
successive commands and then terminating the configuration by entering the end-global
command.
For example, to configure global parameters:
RP/0/RP0/CPU0:router(config)# policy-global
RP/0/RP0/CPU0:router(config-rp-gl)# glbpathtype ebgp
RP/0/RP0/CPU0:router(config-rp-gl)# glbtag 100
RP/0/RP0/CPU0:router(config-rp-gl)# end-global
