Configuring Integrated Routing and Bridging Support for LDP BGP Interworking with VPLS
Beginning with Junos OS Release 9.4, you can configure an integrated routing and bridging
(IRB) interface on a router that functions as an autonomous system border router (ASBR)
in an inter-AS VPLS environment between BGP-signaled VPLS and LDP-signaled VPLS.
Previously, IRB interfaces were supported only on Provider Edge (PE) routers.
NOTE: ACX Series routers do not support configuring IRB for LDP BGP
Interworking with VPLS.
To configure a IRB support for LDP BGP Interworking with VPLS, include the
routing-interface interface-name statement.
You can include this statement at the following hierarchy levels:
•
[edit routing-instances routing-instance-name]
•
[edit logical-routers logical-router-name routing-instances routing-instance-name]
Configuring Inter-AS VPLS with MAC Processing at the ASBR
Inter-AS VPLS with MAC processing at the ASBR enables you to interconnect customer
sites that are located in different ASs. In addition, you can configure the ASs with different
signaling protocols. You can configure one of the ASs with BGP-signaled VPLS and the
other with LDP-signaled VPLS. For more information about how to configure LDP-signaled
and BGP signaled VPLS, see “Configuring Interoperability Between BGP Signaling and
LDP Signaling in VPLS” on page 1274.
For inter-AS VPLS to function properly, you need to configure IBGP peering between the
PE routers, including the ASBRs in each AS, just as you do for a typical VPLS configuration.
You also need to configure EBGP peering between the ASBRs in the separate ASs. The
EBGP peering is needed between the ASBRs only. The link between the ASBR routers
does not have to be Ethernet. You can also connect a CE router directly to one of the
ASBRs, meaning you do not have to have a PE router between the ASBR and the CE
router.
The configuration for the connection between the ASBRs makes inter-AS VPLS with
MAC operations unique. The other elements of the configuration are described in other
sections of this manual.
The following sections describe how to configure inter-AS VPLS with MAC operations:
•

•
Configuring the ASBRs for Inter-AS VPLS on page 1278
Inter-AS VPLS with MAC Operations Configuration Summary
This section provides a summary of all of the elements which must be configured to
enable inter-AS VPLS with MAC operations. These procedures are described in detail
later in this chapter and in other parts of theJunos OS VPNs Library for Routing Devices.
