By default, no remote CCC
connections exist.
Use the
out-interface
keyword
to specify the outgoing interface
only on a point-to-point link. On
other types of interfaces such as
Layer 3 Ethernet interface,
VLAN interface, and Layer 3
aggregate interface, you must
use the
nexthop
keyword to
specify the IP address of the
next hop.
Binding an AC to a cross-connect
This task is mutually exclusive with Ethernet link aggregation. If a Layer 3 Ethernet interface has
been added to a link aggregation group, you cannot bind the Layer 3 interface to a cross-connect,
and vice versa.
When you bind an AC to a cross-connect, you can associate Track with the AC. Then, the AC is up
only when one or more of the associated track entries are positive.
Associating Track with an AC helps detecting AC failure. For example, when an AC is a VE-L2VPN
interface, the interface will not go down upon a link failure because the interface is a virtual interface.
To resolve the problem, you can associate Track with the AC to detect failures on the link that
connects the PE-agg to the L3VPN or IP backbone. When a failure occurs on the link, the VE-L2VPN
interface is set to down. Consequently, the PW bound to the AC goes down. If the PW has a backup
PW, traffic can be switched to the backup PW. For more information about VE-L2VPN interfaces and
L2VPN access to L3VPN or IP backbone, see "
Configuring L2VPN access to L3VPN or IP
."
Binding a Layer 3 interface to a cross-connect
After you bind a Layer 3 interface to a cross-connect, packets received from the Layer 3 interface are
forwarded through the PW or another AC bound to the cross-connect.
