Transmitting Nonstandard BPDUs in Layer 2 VPNs and VPLS

Circuit cross-connect (CCC) protocol, Layer 2 circuit, and Layer 2 VPN configurations can transmit nonstandard bridge protocol data units (BPDUs) generated by other vendors’ equipment. This is the default behavior on all supported PICs and requires no additional configuration.

The following PICs are supported on T Series Core Routers and the M320 Multiservice Edge router and can transmit nonstandard BPDUs:

  • 1-port Gigabit Ethernet PIC

  • 2-port Gigabit Ethernet PIC

  • 4-port Gigabit Ethernet PIC

  • 10-port Gigabit Ethernet PIC
