Command Modes Xconnect configuration
Command History
Usage Guidelines Protocol demultiplexing is supported only for Ethernet and terminated data-link connection identifier
(DLCI) Frame Relay traffic in Cisco IOS Release 12.0(29)S.
Protocol demultiplexing requires supporting the combination of an IP address and an xconnect
command configuration on the IPv4 provider edge (PE) interface. This combination of configurations is
not allowed without enabling protocol demultiplexing, with the exception of switched Frame Relay
permanent virtual circuits (PVCs). If no IP address is configured, the protocol demultiplexing
configuration is rejected. If an IP address is configured, the xconnect command configuration is rejected
unless protocol demultiplexing is enabled in xconnect configuration mode before exiting that mode. If
an IP address is configured with an xconnect command configuration and protocol demultiplexing
enabled, the IP address cannot be removed. To change or remove the configured IP address, the xconnect
command configuration must first be disabled.
Table 7 shows the valid combinations of configurations.
ipv6 Specifies IPv6 as the protocol to demultiplex.
