I don't think they are support BGP4. it's just T1 connection. so i'm looking
for the software solution.
how about i setup the DNS zone record
============
; host to address mapping for abc.com
;
; SOA rec
$TTL 60
@ IN SOA ns1.isp.com. hostmaster.isp.com. (
20010327; serial number
3600 ; refresh after 1 hour
1800 ; retry after 30mins
604800 ; expire after 1 week
60 ) ; minimum TTL of 1 mins
; Name Servers
IN NS ns1.isp.com.
IN NS ns2.isp.com.
IN A 111.111.111.111
IN MX 10 mailserver1.isp.com.
IN MX 10 mailserver2.isp.com.
mail IN A 111.111.111.111
mail IN A 222.222.222.222
smtp IN A 111.111.111.111
smtp IN A 222.222.222.222
* IN CNAME abc.com.
===============
111.111.111.111 is the IP address of mailserver1.isp.com
222.222.222.222 is the IP address of mailserver2.isp.com
mailserver1 will stored the email. mailserver 2 using NFS mount over the
server 1. If the ISP of mail server 1 down. the email user still can receive
their email at mailserver 2. it's another network.
is this work?

In your case, vqalive won't help since the IPs won't be accessible if
the link goes down. What you need is BGP4 support from both ISPs so
the IPs could be routed to the other link...
Best regards,
