R211x-HP Flexfabric 11900 MPLS Command Reference

237
Parameters
route-distinguisher: Specifies an RD, a string of 3 to 21 characters. An RD can be in one of these formats:
• 16 - bit AS numbe r :32-bit user-defined number, such as 101:3.
• 32-bit IP address:16-bit user-defined number, such as 192.168.122.15:1.
• 32-bit AS number:16-bit user-defined number, such as 65536:1. In this format, the minimum value of
the AS number is 65536.
Usage guidelines
MPLS L2VPN uses RDs to differentiate the sites that reside in different VPNs and have the same site ID.
BGP adds the configured RD before the site ID. The RD and the site ID uniquely identify a VPN site.
You cannot configure the same RD for different BGP cross-connect groups.
To change the RD, you must use the undo route-distinguisher to remove the old RD and then use the
route-distinguisher command to configure the new RD.
Examples
# Configure the RD 22:2 for the BGP cross-connect group bbb.
<Sysname> system-view
[Sysname] xconnect-group bbb
[Sysname-xcg-bbb] auto-discovery bgp
[Sysname-xcg-bbb-auto] route-distinguisher 22:2
rr-filter
Use rr-filter to configure the filtering of reflected L2VPN information. The route reflector only reflects the
L2VPN information that contains the specified extended community number.
Use undo rr-filter to restore the default.
Syntax
rr-filter extended-community-number
undo rr-filter
Default
The route reflector does not filter reflected L2VPN information.
Views
BGP L2VPN address family view
Predefined user roles
network-admin
mdc-admin
Parameters
extended-community-number: Specifies an extended community number in the range of 1 to 199.
Usage guidelines
If a cluster has multiple route reflectors, you can configure different filtering policies on the route reflectors
to achieve load sharing.
