Derek,

AFAIK, policy routing is the way to go on this. You might try the following
config out.

                                        !
                ! !---R2---!
        host--!---R1---! !
                ! !---R3---!
                                        !----Server (telnet, ftp, etc)
                                        !

The host wishes to telnet and ftp to the server on the remote network. R1
has two routes to the remote server's network, through R2 and R3. Say you
want to get ftp to run through R2, and telnet through R3...

interface e0/0 <--- this is the common interface with R2 and R3
 ip policy route-map MAP1

route-map MAP1 permit 10
  match ip address 110
  set ip next-hop (R3)
route-map MAP1 permit 20
  match ip address 111
  set ip next-hop (R2)

access-list 110 permit tcp any (Server's net) eq telnet
access-list 111 permit tcp any (Server's net) eq ftp
access-list 111 permit tcp any (Server's net) eq ftp-data

Give this a try. I've not tested it out; I just typed it off the top of my
head, but it should point you in the right direction. Any traffic that does
not match the route maps should be handed back to the route process and
routed accordingly.

Subject: Routing Specific Types of Traffic

Hi,

I was hoping someone could give me some insight into the options that I
have available to me in routing for example FTP traffic through one
interface and Telnet through another.

I understand that policy routing might be a solution. If this is true, does
anyone have a simple config or references on this?

Also, apparently this type of thing can be done at layer 2 because on a
proficiency lab that I have, with two routers connected via Ethernet and
TokenRing, I am supposed to route telnet traffic through E0 and all other
traffic through TokenRing. (apparently involves VLAN's) I understand how to
configure redundancy for VLAN's so that certain ports are blocked for
certain VLAN's unless a link goes down (EO 2/1 and E1 1/2). Maybe this type
of thing goes on top of that?

Thanks,

-Derek
