Configure BGP peer router 1 and 2.
Peer 1 is the primary gateway router. Peer 2 is configured with a metric of "3." The metric
option is key to ensuring gateway traffic is directed to Peer 1, as it will make Peer 2 appear to
be three router hops away from the switch. Thus, the switch should never use it unless Peer 1
goes down.
>> # /cfg/ip/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# las 300
>> BGP Peer 1# ras 100
>> BGP Peer 1# ../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# las 300
>> BGP Peer 2# ras 200
>> BGP Peer 2# metric 3
The metric command in the peer menu tells the Alteon Web switch to create an AS path of "3"
when advertising via BGP.
