Each Layer 2 circuit is represented by the logical interface connecting the local provider edge (PE) router to the local customer edge (CE) router. This interface is tied to the Layer 2 circuit neighbor configured in Configuring the Address for the Neighbor of the Layer 2 Circuit.
To configure the interface for a Layer 2 circuit neighbor, include the interface statement:
-
interface interface-name {
-
bandwidth (bandwidth | ctnumber bandwidth);
-
community community-name;
- (control-word | no-control-word);
-
description text;
-
ignore-encapsulation-mismatch;
-
ignore-mtu-mismatch;
-
mtu mtu-number;
-
protect-interface interface-name;
-
psn-tunnel-endpoint address;
-
virtual-circuit-id identifier;
- }
You can include the interface statement for the Layer 2 circuit neighbor at the following hierarchy levels:
The following sections describe how to configure the interface for the Layer 2 circuit neighbor:
