Dual T-1 to same Provider

Zorker · Sat May 07, 2005 12:16 am

Is it possible yet to combine dual t-1's to the same provider? I see we have bonding, but won't that only work if I have a mikrotik box on the other end doing bonding? I'm in need of a 3mb pipe and I don't want to use a Cisco. Is this the only way? Also, will it make a difference on which T-1 PCI card is used if it can be done?

Thanks

Using MT box only on one end leaves Equal Cost Multipath as the only option:

isn't 2.9 a little different in setup ??

Oh yes, it is. But your question probably was how to set ECMP up on the v2.9, right?

/ip route add gateway=<gw1_IP>,<gw2_IP> check-gateway=arp

Voilà! ECMP with fail-over

But this does not allow me to have a 3mb pipe. I'd like the ability to combine both lines. I want to terminate 2 T-1's into the mikrotik and make it one big pipe instead of buying a Cisco to do it and spending 2x as much. I'm looking at buying a Cyclades dual interface card to do this.

doesnt the pair have to be bonded at the CO(isp provider) ?
in order to bond 2 t1's to make 3mb

Bonding both ways mean you have to be in control of both ends.
If you control only one end your bonding will only work one way and this will require a different bonding technique.

If you want bonding you have to talk this over with your ISP (both T-1's have to come from same ISP and be terminated in the same router on the ISP side). Go ask your ISP what to do.
