10.10 Configuration Examples

This section provides configuration examples for configuring bit-error-triggered protection
switching. Each configuration example consists of the networking requirements, configuration
roadmap, configuration procedures, and configuration files.
10.10.1 Example for Configuring an Association Between Bit Errors
and a Static Route for the Active Link
This section provides an example for configuring an association between bit errors and the static
route for the active link on a network with static native IP and L3VPN services configured.
Networking Requirements
To improve reliability of a network on which static native IP and L3VPN services are configured,
hybrid FRR for static IP routes and VPN routes is configured on PEs at both ends of a native IP
link. To process bit errors that occur on the native IP link, an association between bit errors and
the static route for the active link can be configured, while private network static routes are being
configured on PEs.
In Figure
IP link functions as the active link. A standby link passes through a static LSP between PE1 and
PE2, a static route between PE2 and PE4, and a static LSP between PE3 and PE4.

NOTE
The commands can be configured only on high-speed Ethernet and GE interfaces.
