Hi all,
I have a issue at work that I can't seem to figure out.
It goes like this
6513----portchannel---7204-----2 t-1 to vegas
same 6513---portchannel--7206-1 t-1 to vegas
on the 6513 we have a variance of 2
So I created a acl that that matches all the routes to vegas on the 6513
then I looked from the 6513's perspective to one of those routes to see the metric going to the 7204 and going to the 7206
since the 7204 has 2 T-1s I would like to have the load share have a 2 to 1 ratio with the 7206.
So I took the metric from the 6513 to the 7204 and multiplied it by 1.75 and then subtracted the metric of the 7206 to see what i would have to add in the offset list going to the 7206 to do this load sharing.
7204 default config
Route metric is 5002240, traffic share count is 1
7206
Route metric is 3351040 , traffic share count is 1
so my calculation is 5002240*1.75-3351040
and then the offset list adds 5402880 on the 6513 inbound from the 7206
offset-list 80 in 5402880 Vlan80
So when this is done and i do a sh ip ro for the vegas subnet it only shows routes to the 7204!
Thanks in advance for any help.
