Before You Configure IP

Before you configure IP, you must create the lower-layer interfaces over which IP traffic flows. For information about the modules that support IP:

• See E120 and E320 Module Guide, Appendix A, IOA Protocol Support for modules supported on E120 and E320 routers.
• See ERX Module Guide, Appendix A, Module Protocol Support for modules supported on the ERX310, ERX710, ERX1410, and ERX1440 routers.

For example, to configure an ATM interface:

See JunosE Link Layer Configuration Guide for information about configuring an ATM interface. See JunosE Physical Layer Configuration Guide for information about configuring an Ethernet interface.

Note: If you choose to configure VRRP, we recommend that you complete all IP address configurations before you configure VRRP. See JunosE Services Availability Configuration Guide, for additional information.
