The following lists all of major elements of an inter-AS VPLS with MAC operations
configuration:
Configure IBGP between all of the routers within each AS, including the ASBRs.
Configure EBGP between the ASBRs in the separated ASs. The EBGP configuration
includes the configuration that interconnects the ASs.
Configure a full mesh of LSPs between the ASBRs.
Configure a VPLS routing instance encompassing the ASBR routers. The ASBRs are
VPLS peers and are linked by a single pseudowire. Multihoming between ASs is not
supported. A full mesh of pseudowires is needed between the ASBR routers in all of
the interconnected ASs.
Configure the VPLS routing instances using either BGP signaling or LDP signaling. LDP
BGP interworking is supported for inter-AS VPLS with MAC operations, so it is possible
to interconnect the BGP-signaled VPLS routing instances with the LDP-signaled VPLS
routing instances.
Configure a single VPLS mesh group for all of the ASBRs interconnected using inter-AS
VPLS.

Configuring the ASBRs for Inter-AS VPLS

This section describes the configuration on the ASBRs needed to enable inter-AS VPLS
with MAC operations.
On each ASBR, you need to configure a VPLS mesh group within the VPLS routing instance
which needs to include all of the PE routers within the AS, in addition to the ASBR. You
need to configure the same mesh group for each of the ASs you want to interconnect
using inter-AS VPLS. The mesh group name should be identical on each AS. You also
must include the peer-as all
a single pseudowire to each of the other ASBRs.
To configure the mesh group on each ASBR, include the
statements:
mesh-group mesh-group-name {
peer-as all;
}
You can include these statements at the following hierarchy levels:
[edit routing-instances routing-instance-name protocols vpls]
[edit logical-systems logical-system-name routing-instances routing-instance-name
protocols vpls]
