Example for Redirecting Public IPv4 BGP FlowSpec Routes to SR-MPLS TE Policies

This section provides an example for redirecting public IPv4 BGP FlowSpec routes to SR-MPLS TE Policies to meet the steering requirements of different services.

Networking Requirements

In traditional BGP FlowSpec-based traffic optimization, traffic transmitted over paths with the same source and destination nodes can be redirected to only one path, which does not achieve accurate traffic steering. With the function to redirect a public IPv4 BGP FlowSpec route to an SR-MPLS TE Policy, a device can redirect traffic transmitted over paths with the same source and destination nodes to different SR-MPLS TE Policies.

On the network shown in Figure 1, there are two SR-MPLS TE Policies in the direction from PE1 to PE2. PE2 is connected to two local networks (10.8.8.8/32 and 10.9.9.9/32). It is required that traffic destined for different networks be redirected to different SR-MPLS TE Policies.

Figure 1 Networking for redirecting public IPv4 BGP FlowSpec routes to SR-MPLS TE Policies

Interfaces 1 and 2 in this example represent GE 0/1/0 and GE 0/1/8, respectively.


Precautions

None

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure IS-IS on the backbone network for the PEs to communicate.

  2. Enable MPLS on the backbone network and configure SR and static adjacency labels.

  3. Configure two SR-MPLS TE Policies from PE1 to PE2.

  4. Configure static FlowSpec routes on PE1 and redirect the routes to the SR-MPLS TE Policies.
  5. Configure a tunnel policy.

  6. Establish a BGP FlowSpec peer relationship between the PEs.

Data Preparation

To complete the configuration, you need the following data:

  • MPLS LSR IDs on the PEs and Ps

  • Adjacency labels on the PEs and Ps

Procedure

  1. Configure interface IP addresses.

    After the configuration is complete, you can run the display sr-te policy command to check SR-MPLS TE Policy information.

  6. Establish a BGP peer relationship between the PEs and import local network routes to PE2.

    In this example, loopback addresses 10.8.8.8/32 and 10.9.9.9/32 are used to simulate two local networks on PE2.

    # Configure PE1.

    [~PE1] bgp 100
[*PE1-bgp] peer 3.3.3.9 as-number 100
[*PE1-bgp] peer 3.3.3.9 connect-interface loopback 1
[*PE1-bgp] commit
[~PE1-bgp] quit

    # Configure PE2.

    [~PE2] interface loopback 2
[*PE2-LoopBack2] ip address 10.8.8.8 32
[*PE2-LoopBack2] quit
[*PE2] interface loopback 3
[*PE2-LoopBack3] ip address 10.9.9.9 32
[*PE2-LoopBack3] quit
[*PE2] bgp 100
[*PE2-bgp] peer 1.1.1.9 as-number 100
[*PE2-bgp] peer 1.1.1.9 connect-interface loopback 1
[*PE2-bgp] network 10.8.8.8 32
[*PE2-bgp] network 10.9.9.9 32
[*PE2-bgp] commit
[~PE2-bgp] quit

    After the configuration is complete, run the display bgp peer command on the PEs and check whether a BGP peer relationship has been established between the PEs. If the Established state is displayed in the command output, the BGP peer relationship has been established successfully. The following example uses the command output on PE1.

    [~PE1] display bgp peer

 BGP local router ID : 1.1.1.9
 Local AS number : 100
 Total number of peers : 1                 Peers in established state : 1

  Peer            V          AS  MsgRcvd  MsgSent  OutQ  Up/Down       State  PrefRcv

  7. Establish a BGP FlowSpec peer relationship between the PEs.

    # Configure PE1.

    [~PE1] bgp 100
[~PE1-bgp] ipv4-family flow
[*PE1-bgp-af-ipv4-flow] peer 3.3.3.9 enable
[*PE1-bgp-af-ipv4-flow] commit
[~PE1-bgp-af-ipv4-flow] quit
[~PE1-bgp] quit

    # Configure PE2.

    [~PE2] bgp 100
[~PE2-bgp] ipv4-family flow
[*PE2-bgp-af-ipv4-flow] peer 1.1.1.9 enable
[*PE2-bgp-af-ipv4-flow] commit
[~PE2-bgp-af-ipv4-flow] quit
[~PE2-bgp] quit

    After the configuration is complete, run the display bgp flow peer command on the PEs and check whether a BGP FlowSpec peer relationship has been established between the PEs. If the Established state is displayed in the command output, the BGP FlowSpec peer relationship has been established successfully. The following example uses the command output on PE1.

    [~PE1] display bgp flow peer 

 BGP local router ID : 1.1.1.9
 Local AS number : 100
 Total number of peers : 1                 Peers in established state : 1

  Peer            V          AS  MsgRcvd  MsgSent  OutQ  Up/Down       State  PrefRcv
  3.3.3.9         4         100      208      209     0 02:58:16 Established        0

  8. Configure static BGP FlowSpec route redirection on PE1.

    BGP FlowSpec route redirection is based on <Redirection IP address, Color>. If the redirection IP address and color attributes of a BGP FlowSpec route match the endpoint and color attributes of an SR-MPLS TE Policy, the route can be successfully redirected to the SR-MPLS TE Policy.

    In this example, the traffic destined for 10.8.8.8/32 needs to be redirected to the SR-MPLS TE Policy named policy100, and the traffic destined for 10.9.9.9/32 needs to be redirected to the SR-MPLS TE Policy named policy200.

    # Configure PE1.

    [~PE1] flow-route PE1toPE2
[*PE1-flow-route] if-match destination 10.8.8.8 255.255.255.255

[*PE1-flow-route] apply redirect ip 3.3.3.9:0 color 0:200
[*PE1-flow-route] commit
[~PE1-flow-route] quit

  9. Configure a tunnel policy on each PE to preferentially select an SR-MPLS TE Policy.

    # Configure PE1.

    [~PE1] tunnel-policy p1
[*PE1-tunnel-policy-p1] tunnel select-seq sr-te-policy load-balance-number 1 unmix
[*PE1-tunnel-policy-p1] quit
[*PE1] tunnel-selector p1 permit node 1
[*PE1-tunnel-selector] apply tunnel-policy p1
[*PE1-tunnel-selector] quit
[*PE1] bgp 100
[*PE1-bgp] ipv4-family flow
[*PE1-bgp-af-ipv4-flow] redirect ip recursive-lookup tunnel tunnel-selector p1
[*PE1-bgp-af-ipv4-flow] commit
[~PE1-bgp-af-ipv4-flow] quit
[~PE1-bgp] quit

  10. Verify the configuration.
