Radware Alteon Application Manual page 133

Alteon needs an IP interface for each default gateway to which it is connected. Each interface
needs to be placed in the appropriate VLAN. These interfaces are used as the primary and
secondary default gateways for Alteon.
>> /cfg/l3/arp/rearp 10
>> IP# /cfg/l3/metric strict
>> IP# if 1
>> IP Interface 1# ena
>> IP Interface 1# addr 200.200.200.1
>> IP Interface 1# mask 255.255.255.0
>> IP Interface 1# /cfg/l3/if 2
>> IP Interface 2# ena
>> IP Interface 2# addr 210.210.210.1
>> IP Interface 2# mask 255.255.255.0
4. IP forwarding is enabled by default and is used for VLAN-to-VLAN (non-BGP) routing. Make sure
IP forwarding is enabled if the default gateways are on different subnets or if Alteon is connected
to different subnets and those subnets need to communicate through Alteon.
>> /cfg/l3/frwd/on
Note: To help eliminate the possibility for a Denial of Service (DoS) attack, the forwarding of
directed broadcasts is disabled by default.
5. Globally turn on BGP.
>> # /cfg/l3/bgp/on
6. Configure BGP peer router 1 and 2. Peer 1 is the primary gateway router. Peer 2 is configured
with a metric of 3. The
it makes peer 2 appear to be three router hops away from Alteon. Therefore, Alteon should
never use it unless peer 1 goes down.
>> # /cfg/l3/bgp/peer 1
>> BGP Peer 1# ena
>> BGP Peer 1# addr 200.200.200.2
>> BGP Peer 1# if 200.200.200.1
>> BGP Peer 1# ras 100
>> BGP Peer 1# /cfg/l3/bgp/peer 2
>> BGP Peer 2# ena
>> BGP Peer 2# addr 210.210.210.2
>> BGP Peer 2# if 210.210.210.1
>> BGP Peer 2# ras 200
>> BGP Peer 2# redist/metric 3
