kolawole,

This configuration assumes you have two different ISPs. If you have the same ISP, they can probably do PPP multilink to bundle the circuits together.

Is it possible to bundle the physical interfaces together and have just a single tunnel to the head-office so that i can untilize the 2 links at once?

kolawole,

Separating telnet and http/https traffic to separate interfaces can be done with policy based routing. Redundant routing is easy enough.

However, I am not sure how to accomplish both. I am not sure how to do ‘ip next-hop’ for the primary link and another ‘ip next-hop’ for the secondary.

hi, ur site has been helpful to me for quite a long time now.recently am plague with this issue.
I av a primary link and a backup link in a branch and need telnet traffic to pass 2ru ISP1 and http/https traffic to pass 2ru ISP2 and the traffic to pass 2ru the ACTIVE link in case any of the isp goes down.
The issue is that i do not NAT on my router but instead have a static route 2ru the isps to my HEAD-OFFICE.
And i also have a tunnel from my branch to the HEAD-OFFICE.bellow is a sample config of my branch router.

FYI: On c3845-adventerprisek9-mz.124-15.T1.bin you have support for track 101 rtr 1 reach, but NOT SLA
