# Monitoring the VRF

#### Purpose

Display information about the VRFs in this virtual router: the route target of each VRF and the interfaces attached to each VRF.

#### Action

To display all VRFs in this virtual router:

    host1#show ip vrf
    VRF Name        Default RD         Interfaces
     vpn1           1:1                null0
                                       atm4/0.77
     vpn2           1:3                null0
                                       fastEthernet3/0
                                       atm4/0.21

To display brief information about a specified VRF, specify a VRF name:

    host1#show ip vrf vpn1
    VRF Name        Default RD         Interfaces
     vpn1           1:1                null0

#### Meaning

Table 98 lists the show ip vrf command output fields.

Table 98: 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

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 Fabric Dropped Packets | Number of packets dropped because of internal fabric congestion
VRF | Name of the VRF with which the interface is associated
