Default:
Not configured.
Command Mode:
VRF Configuration Mode.
Usage Guide:
RD can uniquely identify the VPN route. VPN instances realize address space independence via
RD, and thus realize the address overlap between different VPNs. Usually the configuration
includes the AS number and an arbitrary number. RD can’t be deleted directly.
Example:
Switch(config)#ip vrf VRF-A
Switch(config-vrf)#rd 300:3
Switch(config-vrf)#
77.18 route-target
Command:
route-target {import | export | both} <rt-value>
no route-target {import | export | both} <rt-value>
Function:
Configure the Route-Target of the specified VRF 的 Route-Target; The no operation will delete the
configuration.
Parameters:
import: Means to filter the import route, which means to judge whether the VPN route can be added
into the VRF;
export: Means to use the route of this VRF as the Route-Target that will be added to when the
VPNv4 route sends out messages, in order to filter the interface import;
both: Means the import and the export use the same Route-Target;
<rt-value>: Is the the route target value, the format is ASN:nn_or_IP-address:nn. ASN is AS ID,
ranging from 1 to 4294967295, it can be shown in decimal notation (such as 6553700) or delimiter
method (such as 100.100); IP-address is IP address that the length is 4 bytes; nn is arbitrary
number that the length is 2 bytes.
Default:
