Description This command creates an IP interface on top of a VPLS.
The IP interface is created within a VRF instance called vpls-management.
This allows to receive/send IP packets (for example, ANCP) over an MPLS pseudowire (that
is, spoke-spd or mesh-sdp).
Two types of IP interfaces can be created on top of a VPLS, they are distinguished based on
their name:
1) A normal IP interface: the name of this interface should not start with ANCP
2) An ANCP IP interface: the name of this interface must start with ANCP
An ANCP interface has the following syntax: ANCP_X_[Y_]....
The X value represents an integer VLAN value (0 ≤ X < 4096) and is mandatory.
The Y value represents a integer p-bit value (0 ≤ Y ≤ 7) and is optional. When this value is not
specified or when an invalid value is specified, then the default value of 6 is used.
•
When sending a packet over a normal IP interface, the packet which is sent over the
pseudowire is composed as follows:
•
sdp binding of type ether: the MPLS L2 payload is untagged
•
sdp binding of type vlan: the MPLS L2 payload is tagged with the VLAN value specified
as vlan-vc-tag
•
When sending a packet over an ANCP IP interface, the packet which is sent over the
pseudowire is composed as follows:
•
sdp binding of type ether: the MPLS L2 payload is VLAN-tagged with value X (of the
interface name) and p-bit Y
•
sdp binding of type vlan: the MPLS L2 payload is double-tagged with outer VLAN value
X, inner VLAN value vlan-vc-tag and outer p-bit Y
•
Restrictions On a specific VPLS instance all interfaces have to be of the same type (that is, all ANCP
or all normal)
•
The value X of all the ANCP interfaces must be identical for all VPLS instances.
•
This kind of IP interface can only be created on top of a VPLS. Not on top of a v-VPLS.
•
An IP interface can only be created when the VPLS has igmp-snooping disabled.
