Table 1 lists the show ip vrf command output fields.
Table 1: show ip vrf Output Fields
Field Name | Field Description |
|---|---|
VRF Name | Name of each VRF |
Default RD | Default route distinguisher for the VRF |
Interfaces | Interfaces configured for the VRF |
VRF | Name of the VRF |
VRF IP Router Id | IP address that uniquely identifies the router |
Default TTL | Time to live value in the IP header |
Reassemble Timeout | Value to time out reassembled packets |
Interface Configured | Interface configured for the VRF |
Import VPN Route Target Extended Communities | List of VPNs from which the VRF accepts routing information |
Export VPN Route Target Extended Communities | List of VPNs to which the VRF sends update messages |
Import Route-map | Route map associated with the VRF that filters and modifies routes imported to the VRF from the global BGP VPN RIB. The map applies to both IPv4 and IPv6 routes, unless the field name is preceded by IPv4 (applies the map to only IPv4 routes) or IPv6 (applies the map to only IPv6 routes) |
Export Route-map | Route map associated with the VRF that modifies and filters routes exported by the VRF to the global BGP VPN RIB. The map applies to both IPv4 and IPv6 routes, unless the field name is preceded by IPv4 (applies the map to only IPv4 routes) or IPv6 (applies the map to only IPv6 routes). The can filter routes text appears only if the filter keyword was issued for export map. |
Global Import Route-map | Route map associated with the VRF that modifies routes imported to the VRF from the global BGP non-VPN RIB. The map applies to both IPv4 and IPv6 routes, unless the field name is preceded by IPv4 (applies to only IPv4 routes) or IPv6 (applies to only IPv6 routes). |
Global Export Route-map | Route map associated with the VRF that modifies routes exported by the VRF to the global BGP non-VPN RIB. The map applies to both IPv4 and IPv6 routes, unless the field name is preceded by IPv4 (applies the map to only IPv4 routes) or IPv6 (applies the map to only IPv6 routes). |
IP-Address | IP address of the interface |
Status | Status of the interface |
Protocol | Status of the line protocol |
In Forwarded Packets, Bytes | Number of packets and bytes forwarded into an output IP interface |
In Total Dropped Packets, Bytes | Total number of packets and bytes discarded on a receive IP interface |
In Discarded Packets | Number of packets discarded on the ingress interface because of a configuration problem rather than a problem with the packet itself |
In Fabric Dropped Packets | Number of packets discarded on a receive IP interface because of internal fabric congestion |
Out Requested Packets, Bytes | Number of packets and bytes requested to be forwarded out an IP interface |
Out Total Dropped Packets, Bytes | Total number packets and bytes dropped by an IP interface on output |
Out Discarded Packets | Number of packets discarded on the egress interface because of a configuration problem rather than a problem with the packet itself |
Out Fabric Dropped Packets | Number of packets dropped because of internal fabric congestion |
