The following information describes router configuration requirements:
A system interface and associated IP address must be specified.
Boot options file (BOF) parameters must be configured before configuring router parameters.
Confederations can be configured before protocol connections (such as BGP) and peering parameters are configured.
IPv6 interfaces and associated routing protocols may only be configured on the following systems:
7950 XRS systems
7750 SR chassis systems
7750 SR-a chassis systems
7750 SR-e chassis systems
7450 ESS systems with IPv6 functionality limited to those interfaces on slots with 7750 IOM3-XPs/IMMs (or later) line cards.
