NG-MVPN mLDP-based Multicast Configuration Process (IOS-XR)

Architettura di riferimento:

 

 

 

 

STEP-1: enable MPLS mLDP

    mpls ldp mldp

 

STEP-2: configure VRF

    vrf <vrf_name>

    address-family ipv4 unicast (ipv6 unicast per ipv6 protocol)

    import route-target route-target-ext-community

    export route-target route-target-ext-community

       

STEP-3: configure VPN-ID

    vrf <vrf_name>

    vpn id <vpn_id>

 

Nota: la configurazione di un VPN-ID necessità dei profili Rosen mLDP

 

STEP-4: configure MVPN routing and forwarding instance

    multicast-routing vrf <vrf_name>

    address-family ipv4

    mdt default mldp ipv4 root-node

 

Nota:

per il profilo 1 (Rosen mLDP) ” mdt default mldp ipv4 ” command 

per il profilo 4 e 5 (MS-PMSI with BGP A-D) ” mdo partitioned mldp ipv4 mp2mp/p2mp ” command

 

STEP-5: configure Route Distinguisher

    router bgp <as>

    vrf <vrf_name>

    rd <rd_value>

 

STEP-6: configure Data-MDT (optional)

    multicast-routing vrf <vrf_name>

    address-family ipv4

    mdt data <1-255>

 

STEP-7: configure BGP MDT address-family

    router bgp <as>

    address-family ipv4 mdt

 

STEP-8: configure BGP vpnv4 address-family

     router bgp <as>

      address-family vpnv4 unicast

 

STEP-9: configure BGP ipv4 vrf address-family

    router bgp <as>

    vrf <vrf_name>

    address-family ipv4 unicast

 

STEP-10: configure PIM SM/SSM for VRFs

    router pim

    vrf <vrf_name>

    address-family ipv4

    rpf topology route-policy rosen_mvpn_mldp

 

Nota: per ogni profilo una differente route-policy è configutata

 

STEP-11: configure route-policy

    route-policy rosen_mvpn_mldp

     set core-tree tree-type

     pass

    end-policy

 

Nota:

per il profilo 1 (Rosen mLDP) mldp-rosen core tree type

per il profilo 4 e 5 (MS-PMSI with BGP A-D) mldp-partitioned mp2mp/p2mp core tree type
