Common Protocol Suites

JUNOS protocol families include the following common protocol suites:

• Inet—Supports IP protocol traffic, including Open Shortest Path First (OSPF), Border Gateway Protocol (BGP), and Internet Control Message Protocol (ICMP).
• Inet6—Supports IPv6 protocol traffic, including Routing Information Protocol for IPv6 (RIPng), Intermediate System-to-Intermediate System (IS-IS), and BGP.
• ISO—Supports IS-IS traffic.
• MPLS—Supports Multiprotocol Label Switching (MPLS).

If your device is operating in secure context, the Inet6, ISO, and MPLS protocol families are disabled on the device by default. You must enable these protocol families for a device in secure mode to forward IPv6, IS-IS, and MPLS packets. For more information, see Enabling IPv6 in Secure Context, Configuring the IS-IS Protocol, and Enabling MPLS.

Caution: Because MPLS is operating in packet mode, security services are not available.

Note: JUNOS software security processing is not applied to IPv6 or IS-IS packets forwarded by the device.
