Example for Configuring Basic BGP4+ Functions

Example for Configuring Basic BGP4+ Functions

Before building BGP4+ networks, you need to configure basic BGP4+ functions.

Networking Requirements

In Figure 11-9, there are two ASs: AS 65008 and AS 65009. Device A is in AS 65008, and Device B, Device C, and Device D are in AS 65009. BGP4+ must be configured to exchange routing information between the two ASs.

Figure 11-9 Configuring basic BGP4+ functions
NOTE:

Interfaces 1 through 4 in this example are GE 1/0/0, GE 2/0/0, GE 3/0/0, GE 1/0/0, respectively.



Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure IBGP connections between Device B, Device C, and Device D.

  2. Configure an EBGP relationship between Device A and Device B.

Data Preparation

To complete the configuration, you need the following data:

  • Router IDs of Device A, Device B, Device C, and Device D

  • AS numbers of Device A, Device B, Device C, and Device D

Procedure

  1. Configure an IPv6 address for each interface. For configuration details, see Configuration Files in this section.
  2. Configure IBGP connections.

    # Configure Device B.

    [~DeviceB] bgp 65009
    [*DeviceB-bgp] router-id 2.2.2.2
    [*DeviceB-bgp] peer 2001:db8:9:1::2 as-number 65009
    [*DeviceB-bgp] peer 2001:db8:9:3::2 as-number 65009
    [*DeviceB-bgp] ipv6-family unicast
    [*DeviceB-bgp-af-ipv6] peer 2001:db8:9:1::2 enable
    [*DeviceB-bgp-af-ipv6] peer 2001:db8:9:3::2 enable
    [*DeviceB-bgp-af-ipv6] network 2001:db8:9:1:: 64
    [*DeviceB-bgp-af-ipv6] network 2001:db8:9:3:: 64
    [*DeviceB-bgp-af-ipv6] commit
    [~DeviceB-bgp-af-ipv6] quit
    [~DeviceB-bgp] quit

    # Configure Device C.

    [~DeviceC] bgp 65009
    [*DeviceC-bgp] router-id 3.3.3.3
    [*DeviceC-bgp] peer 2001:db8:9:3::1 as-number 65009
    [*DeviceC-bgp] peer 2001:db8:9:2::2 as-number 65009
    [*DeviceC-bgp] ipv6-family unicast
    [*DeviceC-bgp-af-ipv6] peer 2001:db8:9:3::1 enable
    [*DeviceC-bgp-af-ipv6] peer 2001:db8:9:2::2 enable
    [*DeviceC-bgp-af-ipv6] network 2001:db8:9:3:: 64
    [*DeviceC-bgp-af-ipv6] network 2001:db8:9:2:: 64
    [*DeviceC-bgp-af-ipv6] commit
    [~DeviceC-bgp-af-ipv6] quit
    [~DeviceC-bgp] quit

    # Configure Device D.

    [~DeviceD] bgp 65009
    [*DeviceD-bgp] router-id 4.4.4.4
    [*DeviceD-bgp] peer 2001:db8:9:1::1 as-number 65009
    [*DeviceD-bgp] peer 2001:db8:9:2::1 as-number 65009
    [*DeviceD-bgp] ipv6-family unicast
    [*DeviceD-bgp-af-ipv6] peer 2001:db8:9:1::1 enable
    [*DeviceD-bgp-af-ipv6] peer 2001:db8:9:2::1 enable
    [*DeviceD-bgp-af-ipv6] network 2001:db8:9:2:: 64
    [*DeviceD-bgp-af-ipv6] network 2001:db8:9:1:: 64
    [*DeviceD-bgp-af-ipv6] commit
    [~DeviceD-bgp-af-ipv6] quit
    [~DeviceD-bgp] quit

  3. Configure an EBGP connection.

    # Configure Device A.

    [~DeviceA] bgp 65008
    [*DeviceA-bgp] router-id 1.1.1.1
    [*DeviceA-bgp] peer 2001:db8:10::1 as-number 65009
    [*DeviceA-bgp] ipv6-family unicast
    [*DeviceA-bgp-af-ipv6] peer 2001:db8:10::1 enable
    [*DeviceA-bgp-af-ipv6] network 2001:db8:10:: 64
    [*DeviceA-bgp-af-ipv6] network 2001:db8:8:: 64
    [*DeviceA-bgp-af-ipv6] commit
    [~DeviceA-bgp-af-ipv6] quit
    [~DeviceA-bgp] quit

    # Configure Device B.

    [~DeviceB] bgp 65009
    [*DeviceB-bgp] peer 2001:db8:10::2 as-number 65008
    [*DeviceB-bgp] ipv6-family unicast
    [*DeviceB-bgp-af-ipv6] peer 2001:db8:10::2 enable
    [*DeviceB-bgp-af-ipv6] network 2001:db8:10:: 64
    [*DeviceB-bgp-af-ipv6] commit
    [~DeviceB-bgp-af-ipv6] quit
    [~DeviceB-bgp] quit

  4. Verify the configuration.

    # Check the status of BGP4+ connections.

    [~DeviceB] display bgp ipv6 peer
     BGP local router ID : 2.2.2.2
     Local AS number : 65009
     Total number of peers : 3                 Peers in established state : 3
      Peer            V    AS  MsgRcvd  MsgSent  OutQ  Up/Down       State PrefRcv
      2001:db8:9:1::2 4 65009        8        9     0 00:05:37 Established       2
      2001:db8:9:3::2 4 65009        2        2     0 00:00:09 Established       2

    The preceding command output shows that BGP4+ connections have been established between Device B and other routers.

    # Display the routing table of Device A.

    [~DeviceA] display bgp ipv6 routing-table

    The preceding command output shows that Device A has learned routes from its peer in AS 65009. AS 65008 and AS 65009 can exchange routing information.
