Hi

You can make use of PBR here matching the SMTP traffic using ACL and put them in route-map configuring the next hop ip address via the Serial interface.

Here you can match either using based on the SMTP server ip address or even the port being used for the smtp access.

to also have reduandcy kick in when theres some probs with the main link u can add one more ip in addition to the primary next hop ip so that the SMTP traffic may not get affected if theres some link failure with serial interface.

would suggest to check this link for more info on configuring PBR..

Re: Traffic Distribution

You can use policy based routing by creating a route-map combined with an access-list.

ip access-list extended permitSMTP

permit tcp any any eq smtp

ip access-list standard permitAny

permit any

route-map outboundPolicy permit 10

match ip address permitSMTP

set ip next-hop

route-map outboundPolicy permit 20

match ip address permitAny

set ip next-hop

interface

ip policy route-map outboundPolicy
