3.14.3 Checking the Configuration
After configuring VPN FRR, you can view information about the backup next hop (a PE), backup
tunnel, and backup label in the VPN routing table.
Prerequisites
The configurations of the VPN FRR function are complete.
Procedure
l Run the display ip routing-table vpn-instance vpn-instance-name [ ip-address ]
verbose command to check information about the backup next hop, backup tunnel, and
backup label.
----End
Example
Run the display ip routing-table vpn-instance vpn-instance-name ip-address verbose
command on the PE configured with VPN FRR. If information about the backup next-hop PE,
backup tunnel, and label value of the routes is displayed, it means the configuration succeeds.
3.15 Configuring Route Reflection to Optimize the VPN
Backbone Layer
Using an RR can reduce the number of MP IBGP connections between PEs. This not only reduces
the burden of PEs, but also facilitates network maintenance and management.
3.15.1 Establishing the Configuration Task
Before configuring an RR to optimize the VPN backbone layer, familiarize yourself with the
applicable environment, complete the pre-configuration tasks, and obtain the required data. This
can help you complete the configuration task quickly and accurately.
Applicable Environment
The BGP speaker does not advertise the routes learned from IBGP devices to its IBGP peers.
To make a PE advertise the routes of the VPN that the PE accesses to the BGP VPNv4 peers in
the same AS, the PE must establish IBGP connections with all the peers to directly exchange
