<P><FONT SIZE=2>Just FYI, you can terminate multiple GRE tunnels/PPPoE interfaces on something like an RB750 which will get you out of trouble. Cheaper than WICs - you could even buy two, put them hot-failover with a couple of residential DSL modems in Bridge mode. Dirty and horrible, but you get cheap, implied redundancy from the sheer volume of links available...<BR>

I'd check how many of the same WICs are supported in software (whether you can physically insert them is another thing)<BR>
<BR>
Looks like the 2851 supports 4....<BR>

You can use GRE tunnels across the links (or even bypass that completely if you're doing Layer 2) and then use per-packet load balancing on a private AS. Dirty, but it works.<BR>

Hi Guys,<BR>
<BR>
Due to the lack of affordable high bandwidth solutions available up here<BR>
in Mackay, I am entertaining the idea of getting a Cisco 2851 and<BR>
running 6-10 ADSL WIC modules and bonding Telstra ADSL2 links to create<BR>
a 6mbit to 10mbit link. Using a few of NM-2W modules theoretically I can<BR>
fit 10 WIC-1ADSL in a 2851 and load-balance them to make 80mbit/10mbit,<BR>
CEF handling the load-balancing outbound across even metric routes.<BR>
<BR>
Ive had good success in the past doing this with 2 x ADSL2 to make a<BR>
2mbit service but not more than 2. Has anyone tried with 4 or more ?<BR>
<BR>
Any past experiences, thoughts, recommendations appreciated.<BR>
<BR>
Cheers<BR>
<BR>
