Configuring P2MP Tunnels to Bear Multicast Traffic

Configuring P2MP Tunnels to Bear Multicast Traffic

NG MVPN uses P2MP tunnels to bear multicast traffic. You can configure P2MP mLDP or RSVP-TE tunnels as needed.

Context

Both P2MP mLDP and RSVP-TE tunnels can be used to bear multicast traffic. Table 9-2 shows the differences between the two types of tunnels.

Table 9-2 Differences between P2MP RSVP-TE and mLDP tunnels

Category

mLDP Tunnel

RSVP-TE Tunnel

Characteristics

P2MP mLDP tunnels do not support bandwidth reservation and cannot ensure service quality during network congestion. However, mLDP tunnel configurations are more simple than those of RSVP-TE tunnels.

P2MP RSVP-TE tunnels support bandwidth reservation and can ensure service quality during network congestion.

Usage scenario

Networks that do not require control over destination nodes

Networks that do not have high requirements for service quality

Networks that require control over destination nodes

Networks that have high requirements for service quality

Signaling packet transmission

Signaling packets do not need to be periodically sent, reducing network pressure.

Signaling packets need to be periodically sent to maintain the tunnel. If a large number of leaf nodes exist, the network is prone to congestion.

In real-world situations, configure either P2MP mLDP or RSVP-TE tunnels on the ingress node. The type of the tunnel from the intermediate node to the egress is determined by the stitched tunnel's type configured on the intermediate node.

NOTE:

If P2MP RSVP-TE tunnels need to be used, configure a tunnel policy to bind VPN instances to RSVP-TE tunnels.

Procedure

  • Configure the sender PE.
    1. Run system-view

      The system view is displayed.

    2. Run multicast mvpn mvpn-id

      An MVPN ID is set.

    3. Run ip vpn-instance vpn-instance-name

      The VPN instance view is displayed.

    4. Run ipv4-family

      The VPN instance IPv4 address family view is displayed.

    5. Run multicast routing-enable

      IP multicast routing is enabled in the VPN instance IPv4 address family.

    6. Run mvpn

      The VPN instance IPv4 address family MVPN view is displayed.

    7. Run sender-enable

      The PE is configured as a sender PE.

    8. (Optional) Run vpn-target (VPN instance IPv4 address family MVPN view)

      An MVPN target is configured for the VPN instance MVPN address family.

    9. Run c-multicast signaling bgp

      BGP is configured as the signaling protocol for transmitting C-multicast routes.

    10. (Optional) Run either of the following commands to configure the PIM-SM MDT setup mode:

      • To configure PIM-SM MDT setup across the public network, run the rpt-spt mode command.

      • To configure PIM-SM MDT setup not across the public network, run the spt-only mode command.

    11. Run ipmsi-tunnel

      The MVPN I-PMSI view is displayed.

    12. Configure the I-PMSI tunnel setup mode.

      • To configure mLDP as the I-PMSI tunnel setup mode, run the mldp (MVPN I-PMSI view) command.
      • To configure RSVP-TE as the I-PMSI tunnel setup mode, perform the following steps:
        1. Run the mpls te (MVPN I-PMSI view) command to configure RSVP-TE as the I-PMSI tunnel setup mode.

        2. Run the p2mp-template (I-PMSI MPLS TE view) p2mp-template-name command to specify the tunnel template to be referenced by a P2MP RSVP-TE tunnel.

          If the tunnel template specified in the p2mp-template (I-PMSI MPLS TE view) command does not exist, a P2MP RSVP-TE tunnel fails to be set up.You can run the mpls te p2mp-template command to create a tunnel template.

    13. Run commit

      The configuration is committed.

  • Configure the tunnel connection node.
    1. Run system-view

      The system view is displayed.

    2. Run route-policy route-policy-name permit node node

      A route-policy node is created, and the route-policy view is displayed.

    3. Run apply stitch-pmsi { incoming rsvp-te p2mp-template p2mp-template-name | mldp | rsvp-te p2mp-template p2mp-template-name }

      Different types of tunnels are stitched.

    4. Run commit

      The configuration is committed.

    5. Run quit

      The system view is displayed.

    6. Run bgp as-number

      The BGP view is displayed.

    7. Run ipv4-family mvpn

      The BGP—MVPN address family view is displayed.

    8. Run peer peer-ipv4-address route-policy route-policy-name export

      A route-policy is specified filtering routes to be advertised to receiver PEs.

    9. Run commit

      The configuration is committed.

  • Configure the receiver PE.
    1. Run system-view

      The system view is displayed.

    2. Run multicast mvpn mvpn-id

      An MVPN ID is set.

    3. Run ip vpn-instance vpn-instance-name

      The VPN instance view is displayed.

    4. Run ipv4-family

      The VPN instance IPv4 address family view is displayed.

    5. Run multicast routing-enable

      IP multicast routing is enabled in the VPN instance IPv4 address family.

    6. Run mvpn

      The VPN instance IPv4 address family MVPN view is displayed.

    7. (Optional) Run vpn-target (VPN instance IPv4 address family MVPN view)

      An MVPN target is configured for the VPN instance MVPN address family.

    8. Run c-multicast signaling bgp

      BGP is configured as the signaling protocol for transmitting C-multicast routes.

    9. (Optional) Run vrf-route-import compatible draft

      The VRF Route Import Extended Community carried in BGP Update messages is configured to use the format defined in an IETF draft.

      If a non-Huawei device uses the packet encapsulation format defined in an IETF draft, run the vrf-route-import compatible draft command to enable a Huawei device to use the packet encapsulation format defined in the draft so that the Huawei and non-Huawei devices can communicate.

    10. (Optional) Run either of the following commands to configure the PIM-SM MDT setup mode:

      • To configure PIM-SM MDT setup across the public network, run the rpt-spt mode command.
      • To configure PIM-SM MDT setup not across the public network, run the spt-only mode command.

    11. Run commit

      The configuration is committed.
