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

Meaning

Table 99 lists the show ip vrf command output fields.

Table 99: 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).

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
