Hi,
I have 1 ADSL for HTTP and 2 Lease Line for SMTP on the same ISP.
I want to achieve HTTP traffic to be on ADSL while smtp traffic to the lease line. (BGP configuration on 2 lease line).
Please help on my current configuration.

Hello Cinmar1957,
if you want to divert SMTP traffic you should match on it
>>
route-map FOR_SMTP permit 10
match ip address 101
set ip next-hop 12.12.12.1
set ip next-hop recursive 21.21.21.1
!
access-list 101 permit ahp any any
access-list 101 permit udp any any eq isakmp
access-list 101 permit udp any any eq non500-isakmp
access-list 101 permit udp any any eq biff
where is SMTP in the ACL?
Hope to help
Giuseppe

Hello Giuseppe,
Thank you for the reply.
This is the ACL on the running-config:
access-list 101 permit ahp any any
access-list 101 permit tcp any any eq smtp
access-list 101 permit udp any any eq isakmp
access-list 101 permit udp any any eq non500-isakmp
access-list 101 permit udp any any eq biff
access-list 101 deny ip host 0.0.0.0 any
I think I have a problem also about the routing. If the ADSL link goest down, it will not change to LeaseLine Gateway when I show route.
Regards,
Cinmar
