Configuration Examples for ERPS

This section provides ERPS configuration examples.

Example for Configuring an ERPS Single Ring: This section provides an example for configuring an ERPS single ring.

Example for Configuring an ERPS Multi-ring Network: This section provides an example for configuring an ERPS multi-ring network.

Example for Configuring ERPS over VPLS in Scenarios Where a CE Is Dual-Homed to PEs Through VLANIF Interfaces: To configure ERPS over VPLS in scenarios where a CE is dual-homed to PEs through VLANIF interfaces, enable ERPS on PE1, PE2, and the CE and configure ERPS to access the VPLS network in non-virtual channel (NVC) mode.

Example for Configuring ERPS over VPLS in Scenarios Where a CE Is Dual-Homed to PEs Through Ethernet Sub-interfaces: To configure ERPS over VPLS in scenarios where a CE is dual-homed to PEs through Ethernet sub-interfaces, enable ERPS on PE1, PE2, and the CE and configure ERPS to access the VPLS network in non-virtual channel (NVC) mode. Using Ethernet sub-interfaces to access the VPLS network must have the TC notification function enabled so that the VPLS network can have ARP and MAC address entries updated promptly after receiving TC packets. This function, however, does not need to be enabled when VLANIF interfaces are used for VPLS network access.
