Table 1 Command output

Field

Description

IP address

IP address of the next hop.

·     For a P2P link, the IP address of the next hop is not needed. This field displays 0.0.0.0.

·     For an NBMA link, the value 0.0.0.0 indicates the default adjacency entry. Packets are forwarded through the default virtual circuit.

Routing interface

Output interface of the matching route entry.

Physical interface

Physical interface of which the outgoing packets are sent out.

Logical interface

Logical interface for sending the packets. If the entry has no logical interface, this field displays N/A.

Service type/Type

Link layer protocol type. Example protocol types:

·     PPP.

·     HDLC.

·     Tunnel.

·     MTunnel.

Action type

Packet processing type, Forwarding or Drop.

Link media type

Link media type:

·     P2P—Point-to-point link.

·     NBMA—Non-broadcast multi-access link.

VPN index

Index of the VPN.

Virtual circuit information

Information about the virtual circuit, such as PVC or DLCI. If the entry has no virtual circuit, this field displays N/A.

Link head information(IP)

Link layer header for IPv4.

Link head information(MPLS)

Link layer header for MPLS.

 


IPv6 adjacency table commands

display ipv6 adjacent-table

Use display ipv6 adjacent-table to display IPv6 adjacency entries.

physical-interface interface-type interface-number: Displays IPv6 adjacency entries about the specified physical interface.

routing-interface interface-type interface-number: Displays IPv6 adjacency entries about the specified routing interface.

slot slot-number: Specifies an IRF member device by its member ID. If you do not specify a member device, this command displays IPv6 adjacency entries for all member devices.

count: Displays the number of IPv6 adjacency entries.

verbose: Displays detailed information about IPv6 adjacency entries.

Table 2 Command output

Field

Description

IPv6 address

IPv6 address of the next hop.

·     For a P2P link, this field displays N/A. The IPv6 address of the next hop is not needed for a P2P link and is fixed at 0::0 in the packet.

·     For an NBMA link, the value 0.0.0.0 indicates a default adjacency table. Packets are forwarded through the default virtual circuit.

Routing interface

Output interface of the matching route entry.

Physical interface

Physical interface of which the outgoing packets are sent out.

Logical interface

Logical interface that sends the packets. If the entry has no logical interface, this field displays N/A.

Service type

Link layer protocol type. Example protocol types:

·     PPP.

·     HDLC.

·     Tunnel.

·     MTunnel.

Action type

Packet processing type, Forwarding or Drop.

Link media type

Link media type:

·     P2P—Point-to-point link.

·     NBMA—Non-broadcast multi-access link.

VPN index

Index of the VPN.

Virtual circuit information

Information about the virtual circuit, such as PVC or DLCI. If the entry has no virtual circuit, this field displays N/A.

Link head information(IPv6)

Link layer header for IPv6.

Link head information(MPLS)

Link layer header for MPLS.
