two isp T1 links with different networks
Posted on 2014-02-13
we have a branch office with 2 T1 links , one being used for voip traffic and other one for data
since the branch office has grown it seems the bandwidth its sufficient.
Hence I am thinking of bonding the two T1 links together BUT
the way there are setup is not a T1 link would be provided to the customer , I mean the ISP's have their routers on site connected to the T1 and then from there each ISP has given us a Ethernet connection to our router.
On our router we simple router traffic based on destination
DATA = 10.9.199.0/2 - ISP 1
Voice = 192.168.2.1/24 - ISP 2
Question is how can I bond these two together to have T1 (1.5) + T1(1.5) = 3
let me know if I make sense and which method to use
I have in the past configured Multilink on the routers but that would mean terminating the T1 on the router and using ppp on each side
one more thing that both the above networks are reachable from the head office
If I trace DATA network I end up going from one ISP T1 and if Voice network I end up going from second ISP T1.
From DATA and VOICE I can access the Head Office
