Enabling MMRP

When the Multiple MAC Registration Protocol (MMRP) is enabled in the B-VPLS, it advertises the presence of the I-VPLS instances associated with this B-VPLS.

The following example shows a configuration with MMRP enabled.

*A:PE-B>config>service# info
----------------------------------------------
        vpls 11 customer 1 vpn 11 i-vpls create
            backbone-vpls 100:11
            exit
            stp
                shutdown
            exit
            sap 1/5/1:11 create
            exit
            sap 1/5/1:12 create
            exit
            no shutdown
        exit
        vpls 100 customer 1 vpn 100 b-vpls create
            service-mtu 2000
            stp
                shutdown
            exit
            mrp
                flood-time 10
                no shutdown
            exit
            sap 1/5/1:100 create
            exit
            spoke-sdp 3101:100 create
            exit
            spoke-sdp 3201:100 create
            exit
            no shutdown
        exit
----------------------------------------------
*A:PE-B>config>service# 

Because I-VPLS 11 is associated with B-VPLS 100, MMRP advertises the group B-MAC 01:1e:83:00:00:0b) associated with I-VPLS 11 through a declaration on all the B-SAPs and B-SDPs. If the remote node also declares an I-VPLS 11 associated with its B-VPLS 10, then this results in a registration for the group B-MAC. This also creates the MMRP multicast tree (MFIB entries). In this case, sdp 3201:100 is connected to a remote node that declares the group B-MAC.

The following show commands display the current MMRP information for this scenario:
