  • Cisco ASA: BGP routing

    Design & Configure

    Cisco ASA: BGP routing

    Technology: FIREWALLS

    Area: Traffic restrictions

    Vendor: CISCO

    Software: CISCO ADAPTIVE SECURITY APPLIANCE (ASA) , ASA-OS, 8.3+

    Platform: CISCO ASA 5500, 5500-X

     

    BGP runs between routers in different autonomous systems (or the same and then it is called iBGP). BGP routing is supported in Active/Standby and Active/Active HA configurations. Only the Active unit listens on the TCP port for BGP connections from peers.

    ASA migration options

     

    To configure BGP configuration use the command below:

    BGP routing on Cisco ASA

     

    BGP routing configuration example (external BGP – eBGP):


    ----- ASA1 ------
    router bgp 100
    address-family ipv4 unicast
    neighbor 203.0.113.2 remote-as 200
    network 192.168.10.0 mask 255.255.255.0
    network 172.16.20.0 mask 255.255.255.0
    network 10.106.44.0 mask 255.255.255.0


    ----- ASA2 ------
    router bgp 200
    address-family ipv4 unicast
    neighbor 203.0.113.1 remote-as 100
    network 10.10.10.0 mask 255.255.255.0
    network 10.180.10.0 mask 255.255.255.0
    network 172.16.30.0 mask 255.255.255.0
