Hi, Ashwin,
You may try this:
1. Keep those ADSL line along
2. Put the 0.0.0.0/0 route to each ADSL line's peer with same metric.
3. Config the "ip load-sharing per-packet" in each interface.
Please let me know if it works.
Regards,
Jerry

Subject: ADSL Solution
Hi Experts
I need some one to help me out here
- I have 8 adsl lines each 4 MB.The solution I am looking for is
- I need to aggregate the ADSL into one fat pipe of 32MB,the output
of
which shud go to ASA firewall.As the bandwidth is aggregated,it shud
load
balance as well.After the firewall comes Microsoft ISA wherein I
create the
user groups and distribute bandwidth to them.
- The solution I thought was to do ppp multilink on ADSL.i.e i get a
2800 box with some ADSL WICs,but the issue is SP will not do ppp on
his side
.Even if he does the second requirement is that customer wants some
user
groups on Microsoft ISA and he wants some bandwidth allocation to be
done as
per the groups.In which case i can do rate limiting on the router on
the
interface towards the ASA or do rate limiting on ASA provided it
supports.So
the diagram wud look like this.
- SP CLOUD--ADSL LINES----ROUTER---ASA---ISA--LAN
- The second solution if SP does not do PPP multilink is get a
Ethernet
handoff from ADSL modem,put those lines into a Layer3 switch into
seperate
VLANs & then router on a stick .The only issue is i wont have one
big fat
pipe to play with.I will have to play on individual VLANs.The cust
also
wants to create some user groups on Microsoft ISA and he wants some
bandwidth allocated for them.So the only place i can think of doing
some
rate limiting is on the switch or on router on a per VLAN basis
Kindly help me out here.am I missing something.I am a looking for a
Cisco
solution.Is there any Cisco device that can aggregate this ADSL other
than
DSLAM box
