Release Information

Statement introduced before Junos OS Release 7.4.

Option max-sessions-vsa-ignore introduced in Junos OS Release 11.4.

Description

Configure protocol family information for the logical interface.

Note

Not all subordinate statements are available to every protocol family.

Options

family—Protocol family:

  • any—Protocol-independent family used for Layer 2 packet filtering

    Note

    This option is not supported on T4000 Type 5 FPCs.

  • bridge—(M Series and T Series routers only) Configure only when the physical interface is configured with ethernet-bridge type encapsulation or when the logical interface is configured with vlan-bridge type encapsulation. You can optionally configure this protocol family for the logical interface on which you configure VPLS.

  • ethernet-switching—(M Series and T Series routers only) Configure only when the physical interface is configured with ethernet-bridge type encapsulation or when the logical interface is configured with vlan-bridge type encapsulation

  • ccc—Circuit cross-connect protocol suite. You can configure this protocol family for the logical interface of CCC physical interfaces. When you use this encapsulation type, you can configure the ccc family only.

  • inet—Internet Protocol version 4 suite. You must configure this protocol family for the logical interface to support IP protocol traffic, including Open Shortest Path First (OSPF), Border Gateway Protocol (BGP), Internet Control Message Protocol (ICMP), and Internet Protocol Control Protocol (IPCP).

  • inet6—Internet Protocol version 6 suite. You must configure this protocol family for the logical interface to support IPv6 protocol traffic, including Routing Information Protocol for IPv6 (RIPng), Intermediate System-to-Intermediate System (IS-IS), BGP, and Virtual Router Redundancy Protocol for IPv6 (VRRP).

  • iso—International Organization for Standardization Open Systems Interconnection (ISO OSI) protocol suite. You must configure this protocol family for the logical interface to support IS-IS traffic.

  • mlfr-end-to-end—Multilink Frame Relay FRF.15. You must configure this protocol or multilink Point-to-Point Protocol (MLPPP) for the logical interface to support multilink bundling.

  • mlfr-uni-nni—Multilink Frame Relay FRF.16. You must configure this protocol or mlfr-end-to-end for the logical interface to support link services and voice services bundling.

  • multilink-ppp—Multilink Point-to-Point Protocol. You must configure this protocol (or mlfr-end-to-end) for the logical interface to support multilink bundling.

  • mpls—Multiprotocol Label Switching (MPLS). You must configure this protocol family for the logical interface to participate in an MPLS path.

  • pppoe—Point-to-Point Protocol over Ethernet

  • tcc—Translational cross-connect protocol suite. You can configure this protocol family for the logical interface of TCC physical interfaces.

  • tnp—Trivial Network Protocol. This protocol is used to communicate between the Routing Engine and the router’s packet forwarding components. The Junos OS automatically configures this protocol family on the router’s internal interfaces only, as discussed in Understanding Internal Ethernet Interfaces.

  • vpls—(M Series and T Series routers only) Virtual private LAN service. You can optionally configure this protocol family for the logical interface on which you configure VPLS. VPLS provides an Ethernet-based point-to-multipoint Layer 2 VPN to connect customer edge (CE) routers across an MPLS backbone. When you configure a VPLS encapsulation type, the family vpls statement is assumed by default.

    MX Series routers support dynamic profiles for VPLS pseudowires, VLAN identifier translation, and automatic bridge domain configuration.

    For more information about VPLS, see the Junos OS VPNs Library for Routing Devices.

The remaining statements are explained separately. See CLI Explorer.
